It dies. PID and lock files are left hanging but the process is dead.
Might this be DNS related? I've wondered if there is a problem in that
regard because there often appears to be a lot (couple dozen) of dns
requests waiting when I view DNS information in the cache manager. We're
up to 77 redirect_children for squidGuard trying to keep up with the
load. Our traffic usally peaks at around 150 requests a second. I have
also turned off persistent connections because Henrik's suggestion to do
this when we were using squid 2.4 helped a great deal at the time
(though I haven't seen any noticeable improvement this time around).
