Sustained 100% CPU load at ~100/s rates with regular traffic on reasonable hardware is a sign (albeit not a proof!) of a Squid bug (including long searches and similar optimization problems). > During the last time I had a proxy servers CPU reach 100% I ran a > cachemgr export and below is an extract. Next time this happens, consider getting a stack trace or two from the process showing sustained 100% CPU utilization. It is possible to do that without killing the processes (at least on Linux). I do not have step-by-step instructions, but you can find them. Make sure you run (or at least use for getting the stack trace?) an unstripped Squid binary, preferably built with --disable-optimizations. If the place where Squid gets stuck is known, somebody may volunteer to fix the corresponding code. Good luck, Alex. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
