RE: [squid-users] Squid is crashing

Thanks for the prompt response.

Actually I am newbie to debugging I have never used any debugging tool before so no idea of the error I am getting any how I have googled for the last error and be able to install the glibc debuginfo packages but now the error is changed which is like below. So far I am not been able to run gdb as my Program exited with code 01. Please check below:

Look at /var/log/squid/cache.log or /var/log/messages (under BSD) to get the error. If squid stops at boot there is a problem in your config.

You can type also "bt full" when gdb give you the prompt.
