weird cause the site is working but i had some problems with bind for
the last week.

i will try to get a core dump using:
./squid -NCd1

the server is a forward with no interception in a way so i should get
the info from the core dump.
i increased the workers to 4 as the number of cpus in the system.

Thanks,
