Hi Dave,

Are you sure that you did not modify anything substantial in the past 3
days? Firewall rules, sysctl tunables in your FreeBSD box?

The core file suggests that your Squid might have crashed. Are you sure
that there is nothing in your cache.log?

Which firewall do you use to do transproxy? Can you show us your
relevant firewall rules?

Also posting your squid.conf might help. How many users are accessing
your cache normally? If you manually use your proxy server in your web
browser, does it help speed up the web requests?

Thanking you...
