Title: Squid consuming 99% of CPU
Post by: ricardo.claus on Wednesday 23 March 2016, 07:06:40 am
Dear,
To perform deployment testing, I enabled the proxy filter (not transparent) for about 15 users.
They started complaining of slow and pages that do not open. I found that really the pages did not open.
I restarted the service squid and c-icap. He returned to work normally. Minutes later complained again.
I checked the consumption of memory and CPU squid and c-icap. Squid was consuming 99% processing.
My WebFilter has enabled blocking categories. For testing, I disabled the locks (I enabled all filters) and even then the processing consumption is extremely high.
The antivirus is disabled in the web-filter rules.
I am using the Endian 3.0.5, authenticated via NTLM with windows 2012.

Has anyone experienced this problem?

You could try checking your Squid settings against this thread: efwsupport.com/index.php?topic=4095.0;wap2 . This solved one of my issues with slow response from my Endian setup when I first started.

Also, I recall sometime back having a problem with high CPU usage which was to do with an issue with the latest Linux kernel that was released as an update to Endian. The solution was to roll back to a previous working version of the kernel. Sadly, I've lost the link to the forum I found this answer on, but I'm sure a Google search on rolling back to a previous kernel will point you in the right direction.

Dear Gavin 38
I already tried to perform these settings, but did not solve the problem.
Disabled proxy on client machines, so I can perform tests alone.
In tests conducted with only one computer when I open web pages, squid up processing, reaching 50% CPU consumption.
Even performed a efw-upgrade, several updated packages, but the problem still persists.

Dear,

Endian installed the 2.5.2 version, and it works wonderful.
With version 3.0.5 the proxy consumed all the machine's appeal.
Thank you all!
