Is there a suggested NUMTHREADS ? My clients are getting the Squid error page during the day, so I added NUMTHREADS=1024, and recompiled. But now my server is going unresponsive after about 24 hours. I have to reboot RedHat since the process goes DEFUNCT and I can not kill it. I have a dual Xeon P4 3.0 GHZ CPU box and about 10,000 clients.
