Apparent NFS related crashs on PowerEdge 2900 running SLES 10

[Stephan Jansen]

Hi,

We have started seeing what I think are NFS related crashes on a  
PowerEdge 2900.
The machine ran fine during testing for about a month and a half and  
the first
week of production.  After about a week it crashed a few times, then  
ran fine
again for about three weeks.  Now it's crashing frequently.  It seems  
to be NFS
related,  I'm fairly sure I triggered the crash on two or three  
occasions by
installing a large number of RPMs from a directory NFS mounted from  
the server.
It never logs anything to syslog, it locks up hard and does not  
respond to ping
or the keyboard.  The only "fix" is to cycle power.  The only log is  
in the
ESM log.  Here's what it says:

-> omreport system esmlog
Embedded System Management (ESM) Log

Health : Ok

Embedded System Management Log contains...

Severity      : Critical
Date and Time : Fri Apr  6 16:59:39 2007
Description   : System Software event: run-time critical stop was  
asserted

I've talked at length with Dell tech support but the only thing that has
been resolved so far is that it does not seem to be a hardware issue.

Has anyone else seen this problem?   Any fixes or workarounds?

Here's more information on the server:

OS:        SLES 10 x86_64 with all available updates installed
Kernel:    2.6.16.27-0.9-smp
FS type:   xfs
Hardware:  2 x 2.33 GHz Xeon 5140 PowerEdge 2900
