OK... so I tried three runs of the stress-ng memory test (that has been used successfully on every other system we certify for 16.04) and so far, two of three runs have resulted in the system locking up and a bunch of stack trace data dumped to console.

[Bug 1573062] Re: memory_stress_ng failing for Power architecture for 16.04
We're getting zombies here which aren't being reaped: 130428 ?Z 0:00 [stress-ng-brk] 130432 ?Z 0:00 [stress-ng-brk] 130434 ?Z 0:00 [stress-ng-brk] 130436 ?Z 0:00 [stress-ng-brk] The reason for this is that memory stressors like brk have a parent that forks off a child. The child performs the stressing and if it gets OOM'd the parent can spawn off another stressor. So I think the SIGKILL on the stress-ng brk stressor is killing the parent bug the child (which is still holding onto a load of memory on the heap) is not being waited for and hence is in a memory hogging zombie state. We may be in a pathologically memory hogging state because the zombies may be holding brk regions that are swapped out to disk due to memory pressure and we're hitting a low-memory state which is not being cleared up. I suggest modifying the test bash script as follows: 1. run stress-ng with -k flag (so that all the processes have the same stress-ng name) 2. kill with ALRM first 3. then kill with KILL all the stress-ng processes after a small grace period. 4. report on unkillable stressors refer to the changes I made to https://launchpadlibrarian.net/296974522/disk_stress_ng -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573062 Title: memory_stress_ng failing for Power architecture for 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I see that 4.4.0-31-generic-50-Ubuntu passed on all machines across several runs, is that true? 4. Did any of the tests result in system hang? Can we find out from the summary?

This comment is to inform you that mirroring has been disabled between Launchpad bug 1573062 and LTC bug 141723 due to the size of this LP bug attachments. If you want to make this LP bug bridgeable again, I suggest you to remove unwanted attachments or perhaps to compress some of the existing attachments (several large uncompressed text log files currently exist). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573062 Title: memory_stress_ng failing for Power architecture for 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks Jeff. I see that the ARM64 might have failed - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1610320 Can we know the git commit id that fixed the ARM64 failure in mainline? BTW, could you please share the full machine configurations - threads+RAM+swap for each of the other architectures you ran this on? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573062 Title: memory_stress_ng failing for Power architecture for 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Just an additional data point, I ran this test (using Mike's script in a loop) on other architectures: amd64 bare metal: 30 times 4.4.0, no failures amd64 virtual machine: 30 times, 4.4.0, no failures s390 4GB RAM: 40 times on both 4.4.0-31 and 4.7.0, no failures s390 20GB RAM: 40 times on both 4.4.0-31 and 4.7.0, no failures. I'm still running on arm64 and waiting on final results. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573062 Title: memory_stress_ng failing for Power architecture for 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
