[Bug 1785768] Re: [bionic] net-installer dhcp client fails with DHCPDECLINE
This happens to me too - most of the time but not always. I can't identify why dhclient does DHCPDECLINE, the F4 log during installation doesn't have the reason. It is worth noting that my isc-dhcp-server log has warnings like these: dhcpd[26608]: reuse_lease: lease age N (secs) under 25% threshold, reply with unaltered, existing lease for X.Y.Z.W -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1785768 Title: [bionic] net-installer dhcp client fails with DHCPDECLINE To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netcfg/+bug/1785768/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

No memory leaks as far as I can see. By the way, I had to downgrade the kernel above to 3.13.0-65.106 on one server because of some strange IO lockup issues. I'm afraid this won't be of much help, but I'm writing it anyway.

After a couple of days of uptime with 3.13.0-59 it seems there are no leaks, at least not like before. There are no kmalloc-512 allocations by hv_storsvc at all. Total Slab memory is 3.63% of MemTotal, and SUnreclaim is 0.41%. (4GB MemTotal.) Regards, Oskar Liljeblad On Wednesday, September 30, 2015 at 20:28, Oskar Liljeblad wrote: > Hi!

[Bug 1499203] Re: memory leak in hv_storvsc (3.13.0-63-generic)
apport information ** Tags added: apport-collected ** Description changed: Slab and SUnreclaim values in /proc/meminfo keep increasing. On one servers it reached 85% of physical memory after 14 days - but on most other servers it increases more slowly. I checked /proc/slabinfo and almost all allocations were in kmalloc-512. So I enabled "slub_debug=U,kmalloc-512" on one server, and after only 24h of uptime 11% of the memory was used by kmalloc-512 and unreclaimable. With debugging enabled I could see the following in /sys/kernel/slab/kmalloc-512/alloc_calls: 521294 storvsc_queuecommand+0x359/0x790 [hv_storvsc] age=161922/955116/20882927 pid=1-41545 All other counters were below 2000. In /sys/kernel/slab/kmalloc-512/free_calls I see the following: 516823 age=4315783846 pid=0 The hv_storvsc module is for Hyper-V. We are (unfortunately) running Hyper-V 6.3.9600.16384 with Microsoft System Center 2012 R2 Update rollup 3 for all the servers with this issue.

[Bug 1499203] [NEW] memory leak in hv_storvsc (3.13.0-63-generic)
Public bug reported: Slab and SUnreclaim values in /proc/meminfo keep increasing. On one servers it reached 85% of physical memory after 14 days - but on most other servers it increases more slowly. I checked /proc/slabinfo and almost all allocations were in kmalloc-512. So I enabled "slub_debug=U,kmalloc-512" on one server, and after only 24h of uptime 11% of the memory was used by kmalloc-512 and unreclaimable. With debugging enabled I could see the following in /sys/kernel/slab/kmalloc-512/alloc_calls: 521294 storvsc_queuecommand+0x359/0x790 [hv_storvsc] age=161922/955116/20882927 pid=1-41545 All other counters were below 2000. In /sys/kernel/slab/kmalloc-512/free_calls I see the following: 516823 age=4315783846 pid=0 The hv_storvsc module is for Hyper-V. We are (unfortunately) running Hyper-V 6.3.9600.16384 with Microsoft System Center 2012 R2 Update rollup 3 for all the servers with this issue.

[Bug 263435]
10 years+... Why not make it the default that 99% of all browser special keys (Ctrl+1-9, ...) are NOT passed to the plugin, unless the plugin is in a special list of plugins? Or even better something like this: plugin.pass_keystrokes_to_plugins boolean default=true plugin.keystroke_plugin_exclusion_liststring If pass_keystrokes_to_plugins==true, then keystroke_plugin_exclusion_list is a list of plugins not to pass keys to. If pass_keystrokes_to_plugins==false, then keystroke_plugin_exclusion_list is a list of plugins to pass keys to. Would a clean patch implementing this be accepted into mainstream?
