[squid-users] FATAL: Received Segment Violation...dying.

My squid box works fine for the last 2 months. But this morning, it's

When I type 'ps -A | grep squid', I can see the process is still
there, and I can telnet the port squid serves, but I can't browse any
web pages.

Can somebody tell me what's the matter with it?
