Hi Guys, actually all the problem appeared to be happening due to ICP communication between squid and our cache peer which also supports ICP. When we have workers (more than 1) the ICP packets were not returning back (eventually) to the proper worker so that's why the TIMEOUTS were happening, probably due to the reason that this is UDP communication After adding the following simple config # different icp port per worker in order to make it work icp_port 313${process_number} now everything is working fine with Multi worker environment and our cache_peer -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/icp-query-timeout-directive-is-not-working-in-3-3-8-for-some-reason-tp4661324p4661754.html Sent from the Squid - Users mailing list archive at Nabble.com.
