RE: [squid-users] Squid Hang Problem...

Hello Everyone,

        Ray's question has elicited a few questions of my own...

        I have heard of a number of people using a content filter program in
conjunction with squid. I am curious why this would be used over an ACL
built to filter out bad URLs and allow "safe" URLs.

        To me, it would seem that content filtering would be a little more
processor and network intensive of a task. Being that the squid server
would need to download the site, parse the information for questionable
content and then decide whether or not this is a site to allow through.

        With a pair of ACLs checking URLs for questionable keywords and then
allowing through good sites, to me, appears to be less intensive of a
process.

        Anyway, I am curious to know which method is the most recommended to
use. Even though I intend on continuing with my existing method, as it
has been very useful and is very cost-effecive.

        Perhaps my neophyte analysis contains a portion of the answer to Ray's
issue. Maybe his system is becoming bogged down with the content
filtering aspect of his configuration. I suppose the only way to tell is
to keep an eye on the running processes.

        Of course, it might help to have some additional information on what is
happening with the system.

        Ray, if you could take a look at top, you don't need to send that to us.
(It could be a compromise of your system security.) Check to see if
something related to your PERL install could be taking up much more
memory then before, also check the PERL mailing lists and see if anyone
has mentioned anything about memory issues.

        The other information that could help, would be which release of Squid
are you running?

Subject: [squid-users] Squid Hang Problem...

Hello there!
  I just joined the list after searching the Archives, in hopes that
someone may have found an answer to a problem that other people seem to
have but have not had a definite solution to correct it:

  I've been running Squid on our linux gateway since March, in
conjunction with Dansguardian (for Content filtering). Recently, I
upgraded my PERL distribution, and ever since then I've been experiencing
random hangs in Squid: It works for a while (A Day, an hour, a week,
several weeks), and then for no apparent reason it just stops taking
requests, and all my client machines can no longer communicate with it!
(No dns, no ftp, no nothing!) The gateway machine is still running fine,
after I reboot Squid works fine from there. I look at the logs and there
doesnt seem to be any glaring error... Any Ideas of where I should start
troubleshooting at?
