win,

The problem is that you only have 16MB of memory in your client.  I'm 
not sure how much the 8 telnet sessions would require, but the X session 
alone is enough to exhaust your 16MB once you open a few windows.  The 
NFS swapping should prevent it from actually *crashing*, but the 
swapping is probably what you're experiencing when the client pauses for 
a few seconds.  If the client is actually crashing, however, then either 
the client is far into swap and thrashing, or NFS swap really isn't 
working even though you have the setting turned on in lts.conf.  Can you 
determine for certain that NFS swapping is actually working properly?
