Squid 5.2 Memory Usage Continues to Increase in AlmaLinux 9.0

Asked 2 months ago, Updated 2 months ago, 3 views

I run Squid 5.2 on a system with 8GB of memory in AlmaLinux 9.0.
Currently, memory usage is increasing and eventually goes down in one day.

We disable cache, expand file descriptors, etc., but it doesn't improve.

If anyone has any knowledge of this event, please let me know.

Thank you for the squid.conf information.It's almost the default, not SMP or rock.
Does the memory usage continue to increase even if the cache is disabled (cache deny all)?
cache_mem 254MB, so I think the total memory usage is 3 to 4 times that. I wonder why.

Regarding the old document, I think we have no choice but to analyze it using the URL below.


Information about cachemgr.cgi can also be found from the command line at squidclient-p 8080mgr:mem.
