Regarding my previous post, here's some more info. On a 32 GB RAM system, RAM usage grew up to 20GB when I had those "out of memory" messages. After restarting or even shutting down all 5 Squid instances I still get high RAM usage albeit lower than before. # top top - 22:42:23 up 19 days, 15:08, 2 users, load average: 1.30, 1.48, 1.50 Tasks: 342 total, 1 running, 341 sleeping, 0 stopped, 0 zombie %Cpu0 : 1.5 us, 1.5 sy, 0.0 ni, 95.5 id, 0.0 wa, 0.0 hi, 1.5 si, 0.0 st %Cpu1 : 0.0 us, 0.0 sy, 0.0 ni, 98.5 id, 0.0 wa, 0.0 hi, 1.5 si, 0.0 st %Cpu2 : 0.0 us, 0.0 sy, 0.0 ni, 98.5 id, 0.0 wa, 0.0 hi, 1.5 si, 0.0 st %Cpu3 : 0.0 us, 0.0 sy, 0.0 ni, 97.0 id, 0.0 wa, 0.0 hi, 3.0 si, 0.0 st %Cpu4 : 0.0 us, 0.0 sy, 0.0 ni, 97.0 id, 0.0 wa, 0.0 hi, 3.0 si, 0.0 st %Cpu5 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu6 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu7 : 0.0 us, 0.0 sy, 0.0 ni, 95.5 id, 0.0 wa, 0.0 hi, 4.5 si, 0.0 st KiB Mem : 32865056 total, 3679916 free, 17272208 used, 11912932 buff/cache KiB Swap: 37036988 total, 35700916 free, 1336072 used. 15100248 avail Mem A "ps aux --sort -rss" show c-icap in the lead, so I restarted it.

Nothing apparently relevant in the c-icap log though... Has anyone experienced issue such as memory leaks with c-icap and/or squidclamav? I'm using c-icap-0.5.2.
