Hi All,

I have a Centos 4.8 linuxbox running in VMWare ESXi 4 and the kernel is 2.6.9-89.0.11.ELsmp.
Recently, this linuxbox is quite unstable, it has kernel panic once a week... But we didn't have any configuration changes on it.
And I have attached the kernel panic console screen and lsmod for the server.

We have checked the log and there is no useful information...

Are there any awesome tools can help for the investigation or Should we stop the iptables ? Do the kernel panic caused by VM issue?

Since it is a production server, we have scheduled later for the kernel yum upgrade.

Any idea is appreciate.

Thanks,
Frankie

was there any changes done on ESX?
What about vmware tools status for your Centos?

Thank You for your reply.
We didn't make any changes on the ESXi.
What do you mean about vmware tools status?
Are there any tools for checking it?
The vmware-tools version is VMwareTools-4.0.0-175625.

[root@jarvis~]#vmware-checkvm -h
VM's hw version is 4
VMware software version 6 (good)
