After migrating from Squid 2.5.STABLE6 to 2.5.STABLE10 my two squid servers are not sharing cache anymore. Both squids are configured in http accelerator mode and one is a sibling of the other. In the access_log on 10.0.0.2 I see ICP_QUERIES from the other: 10.0.0.1 - - [14/Jul/2005:15:12:09 +0200] "ICP_QUERY http://webserver/page.html HTTP/0.0" 0 50 "-" "-" UDP_HIT:NONE Here the second squid has page.html in cache, but instead of using that, the first squid has a TCP_MISS and is doing a TIMEOUT_DIRECT. 192.168.1.1 - - [14/Jul/2005:15:15:14 +0200] "GET http://webserver/page.html HTTP/1.1" 200 104099 "-" "lwp-request/2.06" TCP_MISS:TIMEOUT_DIRECT How's that possible ? Has anything changed between STABLE6 and STABLE10 in regard to ICP ? This is the configuration I'm using for the cache hierarchy: icp_port 3130 cache_peer 10.0.0.2 sibling 80 3130 acl peers_src src 10.0.0.2 10.0.0.1 acl peers_dst dst 10.0.0.2 10.0.0.1 acl web_access dst webserver acl web_access_port port 80 cache_peer_access 10.0.0.2 allow web_access cache_peer_access 10.0.0.2 deny all http_access allow web_access web_access_port As for the format of the access_log: I've installed the customlog patch.
