Bug#555625: openssh-server: "error writing /proc/self/oom_adj: Operation not permitted" generated when logging into OpenVZ container running linux-image-2.6.26-2-openvz-amd64
Stanislav Tkhorovsky
Version: 1:5.1p1-5
Severity: normal
Each login via SSH into OpenVZ container results in "error writing /proc/self/oom_adj: Operation not permitted" in /var/log/auth.log (the error does not happen when logging into the main server (Hardware Node) - only virtual containers are affected). Using linux-image-2.6.26-2-openvz-amd64 kernel. I am pretty sure that the issue only started manifesting itself after recent kernel upgrade to the above version and had not been present before. The issue can be fixed by changing /etc/default/ssh - setting SSHD_OOM_ADJUST= to empty string gets rid of the error.
