Previously running a non-SMP Squid 3.2.13 instance and according to logs, maxed out at ~500mb of resident after running for hours or days at a time, with a 220mb cache_mem. Now, however the memory usage grows to 900mb in ~40 minutes, and typically reaches 1.5gb in ~4 hours. We have a ulimit in place to kill it once it hits 1.5gb, but prior to putting that in place it typically reached 2gb. > > If you can provide more details I will be happy to try and test it. > > Thanks, > Eliezer If there's any other information you think may be useful, feel free to ask.
