Hello, I have a problem with my server running openvz, I have 5 containers and I have running centos 5.4 in the main node and centos 5.2 in the containers. I have kernel:
2.6.18-164.15.1.el5.028stab068.9PAE #1 SMP
From time to time, the server crashes with a kernel panic and I have to reboot the main node, I can't attach images but this is one example of the kernel message:
Process MailScanner (pid: 8372, veid:406, ti: f2428000 task.ti: f2428000)
Stack: ...

-march 1 2010
-march 31 2010
