Kernel panic and system frozen on DL385 G6

Allen Huang_1 — Thu, 11 Mar 2010 20:05:47 GMT

We have some issues with a few HP ProLiant DL385 G6 dual Six-Core AMD Opteron 2427 @2.20GHz servers recently:

We got errors like:
System1:
Kernel panic – not syncing: nmi watchdog
Kernel panic => reset cleared it

System2:
System frozen
Kernel panic – not syncing: Fatal exception

We recently purchased these systems and they are all running CentOS 5.2

How can we make these systems more stable?

Shalom,

Suggestion 1. CentOS 5 update 4.

Rarely have I encountered a RHEL release that was more bullet proof.

Install HP's PSP package and run monitors.

Boot to NVRAM hardware utils and test all CPU's and memory.

5.2 does not support DL385 Six-Core AMD. You must upgrade to at least 5.3 or higher. I would suggest 5.4 or wait for 5.5 to become GA. 5.5 beta has been released.

Cheers
