We have an RHEL 3 NFS server (cpu AMD Opteron(tm) Processor 240), that
is apparently consistently crashing when I try to extract a large .zip
file (a solaris 8 .iso) from a Fedora Core 2 client with these mount
options:
type nfs (rw,nosuid,intr,hard,timeo=20,rsize=8192,wsize=8192
...and this was in nfsstat:

There was nothing useful in the logs after the crash.
We haven't yet investigated RHEL's network-based crashdump facility.
Would that be helpful?
The server hardware is pretty new, and we had to return it to the vendor
once, because it kept crashing while we copied our homedirs onto its
disk.
Does this sound more like a software problem or a hardware problem?
Anyone seen anything like this? Anyone have any suggestions for
resolving the issue?

Yes! Eminently helpful.... Netdumps are a very good thing....
