Hi all
We're having issues with processes in a container being killed by OOM,
although the hostnode does not have even half of its memory used.
How can it be that there is a failcnt for oomguarpages, although the
barrier wasn't even reached?
This is on Debian Squeeze with the OpenVZ Kernel shipped by Debian.
uname -r
2.6.32-5-openvz-amd64
from dmesg:
