I seem to recall that interrupt() would also cause many types of IO 
operations to abort and exit.  I don't know for sure and I didn't double 
check it.

If it happens at the same time for all clients, have you tried running a 
client locally on your own system so you can observe it directly?  Can 
you run a network trace at the same time?  Can you tell what was being 
sent over the wire immediately before the clients hang?  (Put 
data/commands into a circular buffer then dump the buffer manually.)

What OS does the server run on?  What info/statistics have you tried 
looking at after a hang on the server?
