Subject: 3.10.11 scrub OOM crash
Date: Sun, 10 Nov 2013 10:48:17 +1100 [thread overview]
Message-ID: <201311101048.17277.russell@coker.com.au> (raw)
I've got an AMD64 system with 8G of RAM and 1G of swap. It runs as a home
file server with 2*3TB disks in a RAID-1 array and a 120G SSD for root and
/home. It also does some light desktop work (running KDE and web browsing
with Chromium).
When a btrfs scrub is run from cron the system gives an OOM and then locks up
after apparently killing some processes (after a reboot I see syslog entries
about some processes being killed - even though it didn't appear to kill X or
anything the system is hung).
The system really shouldn't have a OOM. For light desktop use a total of 8G
of RAM and 1G of swap should be more than enough. Most of the time swap is
hardly used and there are several gigs of RAM used for cache.
The kernel is Debian package 3.10.11-1.
This is the same system about which I reported the 3.11.5 kernel infinite loop
bug. I had this crash on scrub issue before I upgraded to 3.11.5. I'm not
certain that 3.11.5 fixed the crash on scrub problem, maybe 3.11.5 just
crashed the system before it could be up for long enough.
