Subject: Still OOM problems with 4.9er kernels
Date: Wed, 30 Nov 2016 08:10:15 +0100 [thread overview]
Message-ID: <aa4a3217-f94c-0477-b573-796c84255d1e@wiesinger.com> (raw)
Hello,
I'm having out of memory situations with my "low memory" VMs in KVM
under Fedora (Kernel 4.7, 4.8 and also before). They started to get more
and more sensitive to OOM. I recently found the following info:
https://marius.bloggt-in-braunschweig.de/2016/11/17/linuxkernel-4-74-8-und-der-oom-killer/
https://www.spinics.net/lists/linux-mm/msg113661.html
Therefore I tried the latest Fedora kernels: 4.9.0-0.rc6.git2.1.fc26.x86_64
But OOM situation is still very easy to reproduce:
1.) VM with 128-384MB under Fedora 25
2.) Having some processes run without any load (e.g. Apache)
3.) run an update with: dnf clean all; dnf update
4.) dnf python process get's killed
Please make the VM system working again in Kernel 4.9 and to use swap
again correctly.
Thnx.
Ciao,
Gerhard
