RE: [squid-users] Problem with SQUID

Hello,
I update this afternoon the proxy (from version 2.5 to version 2.7 STABLE9) as mentioned in the message of Amos Jeffries; I got the version and installed it in less than 10 minutes : I had only 2 problems in the squid.conf file (an option disappeared, and I need to identify the user running squid): the problem is now solved.

Best regards,

Bernard LANDRON

The lines above the FATAL are generally more important, since the error
is logged then a the death shutdown begins. It also gives some info of
maybe some action leading up to the death which may be useful.

Exact cause uncertain.

2.5 is as you say many years old now. It's likely some HTTP feature
becoming common among your users hitting hidden bug. Or maybe a security
flaw that has not been patched and now being hit by someone.
