What is IIRC? if I recall correctly. | 11:21:00 |
 Scrumplex | There are also some other secret providers like KeePassXC | 11:21:02 |
 3von | Oh I c. OK activating keyring now | 11:21:45 |
| 3von | That worked like a charm. Thanks all | 11:23:37 |
 Philip | Hello all. Can anyone suggest why my NixOS system is periodically killing processes with an 'out of memory' status, like this:
Oct 02 10:52:15 pmwhome kernel: Out of memory: Killed process 3118 (dbus-daemon) total-vm:5420kB, anon-rss:0kB, file-rss:2348kB, shmem-rss:0kB, UID:1000 pgtables:48kB oom_score_adj:200
Oct 04 22:55:19 pmwhome kernel: Out of memory: Killed process 2355 (dbus-daemon) total-vm:5420kB, anon-rss:0kB, file-rss:1416kB, shmem-rss:0kB, UID:1000 pgtables:48kB oom_score_adj:200
Oct 05 08:01:44 home kernel: Out of memory: Killed process 2216 (systemd) total-vm:20340kB, anon-rss:0kB, file-rss:1896kB, shmem-rss:0kB, UID:1000 pgtables:80kB oom_score_adj:100
Meanwhile, I have a huge amount of memory:
$ free -m
total used free shared buff/cache available
Mem: 64048 3573 18849 10 41626 59752
Swap: 953851 1525 952326

 K900 | Well presumably you don't have memory at the time | 15:35:11 |
| K900 | Also, swap doesn't really count | 15:35:19 |
| Philip | The kernel would consider it out of memory without using swap? Or what do you mean by doesn't count? | 15:39:23 |
| K900 | The kernel would consider it an out of memory condition if it can't find a page to swap out | 15:41:05 |
| K900 | Which is why you can't just throw swap at your OOM problems and expect them to go away | 15:42:23 |
 ElvishJerricco | Philip: Huh, that's extremely odd; @rosscomputerguy:matrix.org was having a very similar issue in #users:nixos.org the other day | 15:43:30 |
| ElvishJerricco | OOMs on processes that weren't using much memory when the total used wasn't very high | 15:43:46 |
| ElvishJerricco | I think they found out it was some kernel tuning they had done that was the problem. But maybe that was wrong and the problem is somewhere in nixos? | 15:44:44 |
| ElvishJerricco | (also, that is an unbelievable amount of swap. Absolutely a waste lol) | 15:47:56 |
