We compiled from source on RHEL 5.5 to make RPM packages to distribute 
on our RHEL servers.  One machine is still at RHEL 4, and it had its 
RPMs compiled separately.

Yeah, I don't have a core, RHEL sets ulimit to such that none are 
produced.  I'm changing that for the next one.  Once I'm done with some 
long volume transfers, I'll try that problem volume again to see if it 
coughs up a core.

Dumb question:  Would I have to restart bosserver?  Can I do so without 
being disruptive (i.e. restarting the fileserver process) to my users?

Thanks,
