[squid-users] squid stops responding

I have a Debian 2.6.18 box running squid 3.0 and dansguardian 2.8.0.6.
It has been in service almost 3 years without too many problems. When I
came in to work Monday I was informed the internet was inaccessible. The
first thing I did was check that dansguardian had restarted properly
after a logrotate, which it appeared to have. I eventually got around to
doing a restart of squid which worked. Since then squid just randomly
stops responding, the process is running and it's logging page requests
but it never delivers the pages. A restart of squid is the only way to
alleviate the problem. I've looked at the logs and there is nothing
there to indicate what happens, and the log files are not overly large
(one thing I read might cause this to happen). I also pruned the cache.
Any ideas, folks?
