If the Solaris Server is locking up, this is a problem with
Solaris. It might be somehow triggered by Linux, but that is
absolutely no excuse for a server problem. The server should
just stay up.

Sun has some excellent resources available for making certain 
your system is up-to-date. Go over sun.com, and start with the 
support link. They have this patch manager tool which will 
examine your system, figure out what patches it needs, and 
apply them. I don't recall if you need a support contract to
use it or not.

One of the other nice tools they have is their search of their
bugs database system. Here's one which may be related:

#57406: "NFS Server May Panic Upon Receipt of Certain Invalid
Client Requests" Oct 27, 2003.

That's a bad sign. They do list a number of patches for the
issue.

"Sensitive" should refer to performance. My experience is that
Linux NFS clients exhibit horrible performance issues with Sun
servers in standard, out-of-the-box configurations. That's in
comparison to using pure Sun or pure Linux Server/Client
combinations.
