[squid-users] Re: squid-2.7Stable8 hangup

Hi I am facing the same problem but with different messages, any help on this
matter will be highly appreciated.

As I am just a beginner at using squid and linux and I am not even sure
where to dig for the solution. Is it a squid problem or a kernel problem or
some driver problem.

Any help will be highly appreciated.

I am using the same setup as described above by Mr.Felipe
(Bridge+squid+tproxy on an ISP network).

I am using squid 3.2.0.8 with kernel 2.6.38-8 on ubuntu.
