Answering my own post, i've finally found out the cause of this problem (at least on my servers). I've filed a bug report on the openvz bugzilla

https://bugzilla.openvz.org/show_bug.cgi?id=3010

In a nutshell, the sysctl setting

kernel.pid_ns_hide_child = 1

which i used to hide the pids of containers from the HN ps list causes the kernel panic/reboot.

Setting this to 0 will solve the problem, at least for me.

I have replicated this problem on the stab090.5 kernel, vzctl 4.7.2 on both CentOS 5.10 and 6.5
