If both server processes are identical, and are both registering their 
servants with
the same name, then whichever server runs last will be the one registered 
in the
naming service. Since your Solaris server crashes in response to your 
client
request, it seems reasonable to assume that the client was able to resolve 
the
servant's object reference from the naming service entry, so I doubt that 
the problem
lies with the naming service. Perhaps you could post the server code? And 
print
a debug message as the first line of the operation, so you can check 
whether the
correct object/operation was resolved. If the server crashes during the 
operation
then the client will receive a COMM_FAILURE - no surprises there.
