Sorry - maybe I'll post something irrelevant - but my Squid5.3 is running for 3 days now. As it seems the number of user's requests declined (xmas holliday) - the memory consuption stabilized and is not increasing (seemingly - I check only by mrtg figures - I'dont sample memory info because it seemed not prooffing)

Anyway general info shows:

Maximum Resident Size: 48399664 KB Page faults with physical i/o: 171 Memory accounted for: Total accounted: 2013907 KB memPoolAlloc calls: 390527804 memPoolFree calls: 395188267 Max resident size 46GB???


Hi Lukáš ,

This particular value is known to sometimes receive weird/garbage values from the libc API on 64-bit systems, and combines *all* active Squid processes. So be skeptical and prefer OS tools if this matters. Your top output shows a more trustworthy 11 GB resident size for (one of?) the Squid worker process.


Memory allocated total: 2014463 kB. PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND

15487 proxy     20   0   11.6g  11.5g 10344 S   0.0  73.7 103:34.23 (squid-1) --kid squid-1 -YC -f /etc/squid5/squid.conf Is it something not included in the memory utilization chart?

Hopefully not, but it could be something not using Squid Memory pools tracking.


Something tied to connections? requests? ssl contexts? L


"yes maybe" to all the above.
