I'd first look at upgrading it to the latest Squid-2.6.

It looks like its spiralling out of control. Whats the system load at this point? > cache_dir ufs /u01/app/squid-front/cache 100 16 256 You really should be using aufs instead of ufs under Solaris. Solaris has a sane enough threading model for this to work well. It'll drop system load and improve performance. > coredump_dir /u01/app/squid-front/var/cache Could you fire up gdb on that coredump and email me a back trace (using 'bt') ? Adrian
