The open sockets to 127.0.0.1:1344 keep increasing steadily even on high network usage, but they do not decrease when there's little or no traffic. So, day after day the overall number keeps growing until I have to restart squid once or twice a week. In other words, this value keeps growing: Largest file desc currently in use: xxxx This other value can decrease at times, but in the long run it keeps growing too: Number of file desc currently in use: xxxx I tried changing squid parameters such as: icap_io_timeout time-units icap_service_failure_limit icap_persistent_connections on I also tried changing c-icap parameters such as: Timeout MaxKeepAliveRequests KeepAliveTimeout StartServers MaxServers MinSpareThreads MaxSpareThreads ThreadsPerChild MaxRequestsPerChild However, I'm still seeing the same behavior so I reverted back to defaults. This is a small sample of an icap_log taken from Squid: 1515056868.505 9 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff ICAP_OPT/200 353 OPTIONS icap://127.0.0.1:1344/clamav - -/127.0.0.1 - 1515056868.506 10 10.215.246.143 ICAP_ECHO/204 105 RESPMOD icap://127.0.0.1:1344/clamav -
