Problem with squid and squidGuard
-
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=0Try increasing it as per the doc below.

Thanks KOM, i will check and back results to you.

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,5Increase the value after ALL, to get more and more detailed logging.
