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:
