Hi,
I am using squid as a transparent proxy in my network.
I do not need any caching to be done with Squid.
My configuration file is set as follows:
acl all src 0.0.0.0/0.0.0.0
no_cache deny all
cache_dir null /tmp
The process works fine for low load, but under high load I see a surge in t=
he memory usage of Squid process. (it goes upto 200MB and beyond till it ge=
ts killed). Even if I stop the traffic ,this memory is not restored back to=
the system. I even tried setting "memory_pools off". But this does not hel=
p to restore the memory.
Squid version: 2.5 STABLE 9
There is problem #1. Old version of squid.
We are better able to help if you encounter problems in supported
releases (2.6stable17+, 2.7 alphas, 3.0, 3.1 alphas)
How high is the high load? If its under 650 requests/sec then I'd say
upgrade to a 3.x if its more than that you will need 2.6.
cachemgr :info output shows very high Storage Mem size:(about 64MB)
I checked the cachemgr :mem output. One parameter of 'mem_node' seems to be=
consuming high memory. Since I am not using caching is there someway I can=
avoid the usage of high memory in the system using some knob in the squid =
configuration?
All your mentioned knobs for tuning cache are for turning off
disk-cache. Squid still uses a RAM-cache for active objects.
Try this:

Please use Squid 2.6STABLE17+ or 3.0STABLE1+
There are serious security advisories out on all earlier releases.
