      Hi,

      I have a medium network, my users access to internet through squid proxy and we filter sites with squidGuard.

      Currently i have a problem with squid.

      My squid server not response to users after few minutes and when i restart squid service, it works again for few minutes and after some time not responding again! and again, again, again!

      What is a problem and how can i check what goes wrong?

      Best regards.

        If you have a busy network, you may need to spawn more squidguard child threads to keep up. Anything in the System log? Anything in Squid's logs? Anything in squidguard's filter log?

          Yes, i have a busy network.

          How can i spawn child threads of squidguard?

          No any abnormal logs, just a lot of connections in FIN_WAIT_2 state.

          And not any logs...

            Services - Squid Proxy Server - General - Show advanced options - Advanced Features - Integrations has this line:

            url_rewrite_children 16 startup=8 idle=4 concurrency=0

            Try increasing it as per the doc below.

                You may also have to increase the sslcrtd_children value as well.

                  Not change after testing "url_rewrite_children" and "sslcrtd_children".

                  I'm test squid without squidGuard enabled and my problem exists again.

                  squid is not working after few minutes when squidGuard is disabled!

                    There must be something in one of the logs:

                    Status - System Logs - System - General

                    Services - Squid Proxy Server - Realtime

                    Try increasing the squid debug log level by adding this to the Advanced Options - INtegrations section for squid:

                    debug_options ALL,5

                    Increase the value after ALL, to get more and more detailed logging.
