Hi ,
For your information I have installed the same version on two machines one is working fine for staff but this machine which is serving students is creating problem of squid crash.
However In my further analysis I found following in cache.log file seems users deliberately doing some techniques to make the squid crash. Please advise.

Hey there,
This version of squid in not squid but LUSCA which is a fork of squid 2.7.
If you need help about it try contact LUSCA developers.
Since I am not following lusca is dont know anything about their
revisions and maintenance but there are many new features in squid 3+ so
as always I suggest you to try to use squid latest stable.
Best regards,
Eliezer
