Subject: unexpected Out Of Memory (OOM)
Date: Wed, 07 Aug 2013 02:02:20 +0200 [thread overview]
Message-ID: <1375833740.4843.50.camel@localhost> (raw)
Hi,
I have a memory problem on several PV domU, I *suppose* since the
upgrade to 3.10.4 kernel (and still occur with 3.10.5).
I use Xen 4.2.2 (from Debian sid), and the dom0 run under Debian Wheezy
with a vanilla 3.9.11 kernel.
The problem : once a domU throw oom-killer, then it loop until all
processes will be killed, then the kernel abort and shutdown the VM.
I'm not sure how to read the OOM-killer messages about memory state, so
I copy/paste a list of them here, about a 2GB RAM domU :
