I had a similar problem; when a container ran out of memory the host crashed:


[ 5030.259197] Fatal resource shortage: privvmpages, UB 1211.
[ 5030.286759] Fatal resource shortage: privvmpages, UB 1211.
[ 5030.308249] Fatal resource shortage: privvmpages, UB 1211.

..
.

I can reproduce this bug with the "official" debian-kernel (linux-image-2.6.26-1-openvz-amd64).

The updated kernel

http://people.debian.org/~dannf/bugs/500876/linux-headers-2.6.26-1-openvz-amd64_2.6.26-14~dannf.1_amd64.deb

fixes the problem: Instead of a kernel panic processes inside the container get killed (expected behaviour) .

Thanks a lot!


Will this fix go into the official kernel? If you need additional testing, oder some more kernel-traces, please let me know.
