RE: [squid-users] sometimes the users can´t visit any webpage

Hi, thanks for your interest

Well, today I had same problem, this is an extract to my cache.log. The
problem happened about 15:30hrs, and the user reported me about 16:00 hrs,
and I had to restart the "squid service".

Any Idea? What does it mean "httpReadReply Excess data from..."?

Have you checked cache.log for the special requests?
Only the info on cache.log (or with debug level) is valuable.
