Hi Ed,

First, I feel your pain.

While I don't have an answer, I did switch from OSX based Samba server  
to Linux and my problems went away.

My experience in general with OSX server 10.5 is that its a horrible  
XSAN, NFS, AFP, SMB server.

What I've used to help trouble shoot OSX in general in addition to the  
built in process viewer is XRG ( X Resource Grapher).

You can also try to dtrace stuff.  Just type it in a term to see some  

There were some NFS bugs I uncovered and shared with the OSX Server  
dev guys which should be fixed in 10.6 server but who knows if that  
will also fix the plethora of other issues.
