CVS hanging in checkout

[George]

Server:cvs version 1.11.5 on Solaris 2.8
Client:cvs version 1.11.5 on Solaris 2.8

Trying any CVS checkout results in a hanging process.  The files are
checked out, but the process never completes.  This only happens on
the first checkout, and this problem doesn ont occur when I use a
Windows client.  A subsequent checkout (as long as I don't delete the
checked out module) of the checked out module works fine.  Any help
would be great.  Other posts I've read on this seem inconclusive...I
hope someone has found something new.  I pasted the trace below (I can
include more if it will help):

(Here is where it hangs.  Control-C gets out of this, but kill on the
process results in <Defunct> process that remains.
