Hi, after upgrading to opensuse 13.1, squid3.4 (same with current 3.HEAD) leaks memory after a short time and stops responding to snmp queries(not sure if that's related). In a test setup i can reproduce the issue as follows: Test with 100 rps: Everything good Test with 250 rps: After some minutes, only 100 to 200 requessts pass, memory increases with constant speed, some snmp queries fail (timeout) or take longer to process, nothing in log Test with 500 rps: Only around 100 queries pass, memory increases faster, most snmp queries fail, nothing in logs Same with 1 or multiple workers. In cachemgr, i see that Cumulative allocated volume continues to increase to values like 7 GB while actual VIRT mem is 300MB, RSS 160MB Any ideas how to fix this or otherwise how to get more debug information? -- Best Regards Nils Hügelmann
