Hello,
I am experiencing the same Problem as Hugo Deprez reported and i
think it is a memory leak.
In my case i can confirm this memory leakage for Squid releases
3.2.0.18 and 3.2.0.19.
We have a few hundred users using our Squid Proxy VM (4 Cores/4 GB
RAM/Ubuntu 12.04/x64) and during work hours memory useage is
increasing quite quickly (e.g. in 1 hour 15% increase of RAM useage
by
Squid).
After a few hours my Squid Proxy VM begins to swap:
Mem: 4049728k total, 3943484k used, 106244k free, 7836k
buffers
Swap: 2097148k total, 826108k used, 1271040k free, 117900k
cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
26177 proxy 20 0 4159m 3.4g 2160 S 3 87.0 29:20.81 squid3
also adding:
Can you try tuning these options?
memory_pools off
memory_pools_limit 1 MB
as suggested by Drunkard Zhang does not help.
...
So, how can we help to track down this problem?
I think this is probably:
http://bugs.squid-cache.org/show_bug.cgi?id=3605
Can you start with the cachemgr memory usage report and confirm whether
the same FwdServer excessive memory usage is seen?
