Morning all. We've been experienceing regular cluster crashes on RHEL4u4.
This system has 5 nodes and a few dozen nodes mounting shares via nfs.
Periodically, nodes will panic, get fenced and all continues on. This system
does have some of the HP Product Support Pack installed (not the HP bnx2
driver). Below is the section from the logs. It is hand typed but I am fairly sure
it's accurrate.
The machines are HP DL360-G5's. The nics are Broadcom NeXtreme II 5708's.
Anyone else seeing this?
