Hi,
my server has crashed twice now on the RHEL6 042stab033.1 kernel. I'm running OpenVZ on a Dell 1950. I get the following in /var/log/messages

Aug 23 23:23:29 aunode3 kernel: imklog 4.6.2, log source = /proc/kmsg started.
Note I have added a small patch to this kernel myself however I don't believe my patch would have any significant effect, its a tiny simple patch that adds function of putting a process to sleep. I'm not using this feature at all atm, it needs to be activated before it does anything and its off by default.
After rebooting the oops comes right back again but the server keeps running ok until it crashes at random time, usually about a week or 2 later.
Any ideas? How to get this fixed?
