swap storms kills interactive use

Bug description:
[Impact]
The i915 shrinker can make the system unresponsive and kill
interactive performance by swapping out dirty objects to reclaim more
memory.
[Test case]
The problem can be easily reproduced running an I/O intensive writer,
for example:
$ dd if=/dev/zero of=/tmp/zero bs=1G count=32
When the system is running out of memory and the i915 shrinker is
called we can experience noticeable lags in the normal interactive
activities (mouse not responding for 5-10 seconds, screen not
refreshing, etc.).
[Fix]
Avoid the lags by preventing to swap out dirty objects in the i915
shrinker (other cached objects can still be reclaimed).
[Regression potential]
The right fix would be to backport commit 2850748ef876 ("drm/i915:
Pull i915_vma_pin under the vm->mutex"), available in v5.5+. However
the backport is not trivial and the risk to introduce other bugs is
high.
A simple change like this (it's basically a one-liner that removes a
flag) can be a reasonable compromise to prevent the problem and avoid
the risk of introducing other bugs.
[Original report]
Hello, several times since upgrading to focal from 19.04 I've found my
computer entirely unresponsive for periods of twenty or thirty
seconds. No mouse movement, no keyboard input, the screen output does
not change.
My computer was using swap space and despite very slow writeout speeds
well below what the NVME drive can handle, the computer was unusable.
I've captured some vmstat 1 output and top output that I started
collecting during the event. (Normally one very long painful period is
followed by several shorter periods of uselessness.)
Thanks

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
** Description changed:
[Impact]
- High watermark boosting can cause large swap activity under certain
- memory intensive workloads, making the system very unresponsive (screen
- does not refresh, keyboard not responding, etc.).
-
- This large swap activity seems to be prevented disabling high watermark
- boosting.
+ The i915 shrinker can make the system unresponsive and kill interactive
+ performance by swapping out dirty objects to reclaim more memory.
[Test case]
- Opening this web page in chrome seems to be a good reproducer of the
- problem:
+ The problem can be easily reproduced running an I/O intensive writer,
+ for example:
-
https://platform.leolabs.space/visualizations/conjunction?type=conjunction=2004981040
+ $ dd if=/dev/zero of=/tmp/zero bs=1G count=32
- When this page is opened we can clearly see from 'top' (for example)
- that the used swap is going up very quickly.
-
- With the fix applied swap is not used at all and the system is always
- responsive.
+ When the system is running out of memory and the i915 shrinker is called
+ we can experience noticeable lags in the normal interactive activities
+ (mouse not responding for 5-10 seconds, screen not refreshing, etc.).
[Fix]
- Set vm.watermark_boost_factor to 0, disabling watermark boosting by
- default.
+ Avoid the lags by preventing to swap out dirty objects in the i915
+ shrinker (other cached objects can still be reclaimed).
[Regression potential]
- Regression potential is minimal, setting vm.watermark_boost_factor to 0
- by default restores the old kernel behavior before watermark boosting
- was introduced. In case of unexpected regressions we can always fix this
- in user-space via sysctl.
+ The right fix would be to backport commit 2850748ef876 ("drm/i915: Pull

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
Seth, thanks for the update! JFYI, I've just upladed also a v3 kernel (5.4.0-24.28+lp1861359v3) that I'm currently testing on my laptop with positive result. This change is even smaller than the previous one (v2), because we simply disable the direct swap out in the i915 shrinker (I915_SHRINK_WRITEBACK). It's really a one-line change, so the regression potential is very minimal. If I don't find any problem I would consider to include this last fix. It would be great if you could also do a test with this one (so please ignore the v2 kernel).

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
Andrea, I've been running the v1 kernel for a day or so now: [0.00] Linux version 5.4.0-24-generic (arighi@sita) (gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu1)) #28+lp1861359v1 SMP Wed Apr 15 14:49:33 UTC 2020 (Ubuntu 5.4.0-24.28+lp1861359v1-generic 5.4.30) $ uptime 02:21:45 up 1 day, 9 min, 14 users, load average: 0.42, 0.25, 0.23 and have not seen any hangs or stalls of any sort in the ~ten hours that I've been using it. Normally these problems start to appear about a day into use, so it's perhaps still early to declare success, but this is looking promising. Even loading https://platform.leolabs.space/visualization in firefox just causes momentary glitches in mouse movement, like 50ms kind of range.

I've uploaded another test kernel (5.4.0-24.28+lp1861359v2): https://kernel.ubuntu.com/~arighi/LP-1861359/ In this one, instead of completely disabling the i915 shrinker, I'm only preventing to swap out the i915 caches when the system is short on memory. I'm testing this new one on my laptop right now and it seems to be a better compromise, since it still allows to free up some i915 memory, but it also prevents to completely kill interactive performance. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Status in linux source package in Focal: Confirmed Bug description: [Impact] High watermark boosting can cause large swap activity under certain memory intensive workloads, making the system very unresponsive (screen does not refresh, keyboard not responding, etc.).

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
Hi Seth, sorry for my late response. I did more tests this morning on my laptop tracing the callers of __alloc_pages_nodemask() and I noticed that pretty much all the time it is called by the i915 shrinker. So I tried to disable it and I have to say that on my laptop (at least) the system is always very responsive now even when the system is swapping out pages and I generate a lot of I/O. I've uploaded this test kernel here (5.4.0-24.28+lp1861359v1): https://kernel.ubuntu.com/~arighi/LP-1861359/ Can you do one more test with it and verify if it does some improvements also in your case? Probably it's not yet a valid solution, but if it works it would tell us that the problem is exactly there.

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
TL;DR @seth-arnold, as a test can you try to set the following options? $ echo $((32 * 1024 * 1024)) | sudo tee /proc/sys/vm/dirty_bytes $ echo $((32 * 1024 * 1024)) | sudo tee /proc/sys/vm/dirty_background_bytes Repeat the test and see if the system is still unresponsive. Details below. This is what I think it's happening in this last scenario: interactive performance killed when a large I/O writer is running. The large I/O writer generates a lot of dirty pages, nothing is forcing to sync those pages to the backing store until the dirty_ratio (=20%) / dirty_background_ratio (=10%) thresholds are hit. And they can be quite high with the default settings in systems with a lot of RAM. For example in a system with 16GB of free/reclaimable memory, the amount of dirty memory that is allowed before a writer is actively forced to flush those pages to the backing store is: 16GB * 20 / 100 = 3.2GB. Flusher threads are started when the amount of dirty pages is 16GB * 10 / 100 = 1.6GB of dirty memory. So, if the writer doesn't stop, it will consume all the free pages in the system and at that point we are going to have a lot of dirty pages. Then the kernel needs to decide what to do to free up some pages. Reclaimable memory is the first choice: cached clean pages that already have a copy on the corresponding backing store are easy to reclaim, because they just need to be dropped from the page cache (no I/O involved). Dirty pages are more expensive to reclaim, because they need to be flushed to the backing store before freeing up the page. Same with anonymous memory that needs to be flushed to the swap device, before being able to re-use the page. So when the system starts to reclaim some pages, we see some swap activity and we also see some I/O due to the flushing of the dirty pages. I think the system becomes sluggish, because there are too many dirty pages, the kernel is spending too much time to select the right pages to reclaim and interactive performance is killed. This looks like a bug/regression in the kernel and I think we should definitely investigate more and track down the reason of the problem. In the meantime, as a test to prove this thoery I think we could try to reduce the amount of allowed dirty pages in the system, tuning the dirty thresholds: vm.dirty_bytes and vm.dirty_background_bytes (using the *_bytes tuners to have a more fine-grained control on those thresholds) and see if there are some benefits in the specific scenario reported by Seth. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Status in linux source package in Focal: Confirmed Bug description: [Impact] High watermark boosting can cause large swap activity under certain memory intensive workloads, making the system very unresponsive (screen does not refresh, keyboard not responding, etc.).

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
Sultan, thanks for the advice. I set this watermark boost factor to zero as you suggested, and then decided to try a stupid simple benchmark of my storage -- my swap is a zfs dataset on nvme. zfs means it'll go slower than raw nvme block access: $ dd if=ubuntu-18.04.4-desktop-amd64.iso of=foo bs=$((1024*1024)) conv=fsync 2028+1 records in 2028+1 records out 2126544896 bytes (2.1 GB, 2.0 GiB) copied, 6.91399 s, 308 MB/s And this is a sequential workload with large blocks rather than random with pages, but it gives the flavour of the speed well enough. Anyway, my system hung again when re-focusing firefox even after changing the watermark boost factor to zero. It was unusable for ten or twenty seconds. I have loads of free memory, it shouldn't be in swap: $ free -h totalusedfree shared buff/cache available Mem: 15Gi11Gi 1.6Gi 643Mi 2.2Gi 2.8Gi Swap: 2.0Gi23Mi 2.0Gi Thanks -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Bug description: [Impact] High watermark boosting can cause large swap activity under certain memory intensive workloads, making the system very unresponsive (screen does not refresh, keyboard not responding, etc.).

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
This problem is caused by an upstream memory management feature called watermark boosting. Normally, when a memory allocation fails and falls back to the page allocator, the page allocator will wake up kswapd to free up pages in order to make the memory allocation succeed. kswapd tries to free memory until it reaches a minimum amount of memory for each memory zone called the high watermark. What watermark boosting does is try to preemptively fire up kswapd to free memory when there hasn't been an allocation failure. It does this by increasing kswapd's high watermark goal and then firing up kswapd. The reason why this causes freezes is because, with the increased high watermark goal, kswapd will steal memory from processes that need it in order to make forward progress. These processes will, in turn, try to allocate memory again, which will cause kswapd to steal necessary pages from those processes again, in a positive feedback loop known as page thrashing. When page thrashing occurs, your system is essentially livelocked until the necessary forward progress can be made to stop processes from trying to continuously allocate memory and trigger kswapd to steal it back. This problem already occurs with kswapd *without* watermark boosting, but it's usually only encountered on machines with a small amount of memory and/or a slow CPU. Watermark boosting just makes the existing problem worse enough to notice on higher spec'd machines. To fix the issue in this bug, watermark boosting can be disabled with the following: # echo 0 > /proc/sys/vm/watermark_boost_factor There's really no harm in doing so, because watermark boosting is an inherently broken feature... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Bug description: Hello, several times since upgrading to focal from 19.04 I've found my computer entirely unresponsive for periods of twenty or thirty seconds.

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
There is an interesting (to me, anyway) change of behaviour with the -17 kernel: while earlier kernels would appear to be locked solid for 30-60 seconds before the screen could update, -17 allows screen updates every six seconds or so. I have an always-running mosh session to a remote host running irssi. This session has a clock that updates every second. When this problem strikes I can glance at this clock and by watching the time jumps, gauge how long the hangs are. When the -17 kernel hangs during these events, this clock updates roughly every six seconds: eg on seconds 36, 42, 48, 54, 00, 06, 13, 19, 25, 31, 37, 43, 50, 56.. The system is by no means usable during this time, but it is interesting that enough userspace ran for mosh to accept packets and redraw the urxvt terminal, and xorg to update the screen. My most recent hang happened while firefox loaded https://www.google.com/maps/place/20%C2%B054'35.7%22S+55%C2%B035'05.0%22E/@-20.9099167,55.5826253,2281m/data=!3m2!1e3!4b1!4m5!3m4!1s0x0:0x0!8m2!3d-20.90991!4d55.58471 but it might be the case that this is just what pushed my browser over the edge, after loading several pages of google docs content and a PDF.

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
I guess we can't use ftrace and secure boot at the same time then... would it be possible to disable secure boot / kernel lockdown on your side and run a test using that kprobe-perf command? If it's not possible or too complicated we'll find an alternative way, maybe I can create a custom kernel and add some specific code to trace shrink_node(). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Bug description: Hello, several times since upgrading to focal from 19.04 I've found my computer entirely unresponsive for periods of twenty or thirty seconds.

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
Ah! You're right, that's the reason! When the kernel is locked down ftrace is explicitly disabled. To confirm that, you should have 0 in /proc/sys/kernel/ftrace_enabled. Can you try to set it back to 1 and see if kprobe-perf works after that? Otherwise I'll figure out an alternative way to trace down the swapping issue.

Unfortunately, this did not solve the problem.

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
OK, so we know that it's not related to the memory cgroup subsystem. Another reason of such unexpected swapping activity could be due to memory compaction code that is triggering some direct memory reclaim and forcing to swap out pages. What do you have in /proc/sys/vm/swappiness? Could you try to set that to 0 (kernel prefers to drop file-backed pages instead of swapping out anonymous pages) and see if the swap out activity is still happening? Moreover, we can do some more advanced tracing of the direct memory reclaim code, for example: $ sudo kprobe-perf -s 'p:shrink_node' This may give us useful information if and how direct memory reclaim code was triggered (this command should print out some stack traces when notice the swap out activity). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Bug description: Hello, several times since upgrading to focal from 19.04 I've found my computer entirely unresponsive for periods of twenty or thirty seconds.

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
Hello Seth, thanks for reporting the problem. I was wondering if this could be related to the memory cgroup controller. As a simple test could you try to reboot the system adding cgroup_disable=memory to the kernel boot parameters? In this way if the problem goes away at least we know it's related to the memory cgroup and we can investigate more (it could a misconfiguration enforced by systemd or a recent change in the kernel that introduced this different behavior). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Bug description: Hello, several times since upgrading to focal from 19.04 I've found my computer entirely unresponsive for periods of twenty or thirty seconds.

FYI, I decided to do this: $ sudo swapoff -a && sudo swapon -a $ free -h totalusedfree shared buff/cache available Mem: 15Gi 5.9Gi 4.8Gi 2.0Gi 4.8Gi 7.2Gi Swap: 15Gi 348Mi15Gi Even though I am no where near needing to swap, after the swapoff/swapon, it immediately climbed back up to 348M. Oddly, I did it again after flushing the page cache, and the swap stayed at zero: $ sudo sync ; sudo sh -c 'echo 1 > /proc/sys/vm/drop_caches' $ sudo swapoff -a && sudo swapon -a $ free -h totalusedfree shared buff/cache available Mem: 15Gi 5.6Gi 6.8Gi 2.6Gi 3.1Gi 7.0Gi Swap: 15Gi 0B15Gi I don't know if flushing the page cache is related or coincidence with the second swap clearance. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Bug description: Hello, several times since upgrading to focal from 19.04 I've found my computer entirely unresponsive for periods of twenty or thirty seconds.
