[Samba] Server crash - Is it a Kernel or Samba problem?

[Trimble, Ronald D]

Yesterday I had an unexpected server crash.  Here is what appeared in the logs:

My question is is this a kernel or a samba problem?  Has anyone experience this before?  I do know that the server was under considerable SMB load (a build was being generated on another computer and written to this server) when the oops occurred.  I am running SUSE SLES 9 SP4.  Kernel is 2.6.5-7.286-bigsmp.

Any help would be appreciated.  Thanks!
