Given the following config lines: ###Userserve cache_peer 10.0.20.1 parent 81 0 no-query originserver no-digest no-netdb-exchange name=userserve1-81 carp weight=1 cache_peer_domain userserve1-81 userserve.last.fm cache_peer 10.0.20.1 parent 82 0 no-query originserver no-digest no-netdb-exchange name=userserve1-82 carp weight=1 cache_peer_domain userserve1-82 userserve.last.fm cache_peer 10.0.20.1 parent 83 0 no-query originserver no-digest no-netdb-exchange name=userserve1-83 carp weight=1 cache_peer_domain userserve1-83 userserve.last.fm cache_peer 10.0.20.1 parent 84 0 no-query originserver no-digest no-netdb-exchange name=userserve1-84 carp weight=1 cache_peer_domain userserve1-84 userserve.last.fm cache_peer 10.0.20.2 parent 81 0 no-query originserver no-digest no-netdb-exchange name=userserve2-81 carp weight=1 cache_peer_domain userserve2-81 userserve.last.fm cache_peer 10.0.20.2 parent 82 0 no-query originserver no-digest no-netdb-exchange name=userserve2-82 carp weight=1 cache_peer_domain userserve2-82 userserve.last.fm cache_peer 10.0.20.2 parent 83 0 no-query originserver no-digest no-netdb-exchange name=userserve2-83 carp weight=1 cache_peer_domain userserve2-83 userserve.last.fm cache_peer 10.0.20.2 parent 84 0 no-query originserver no-digest no-netdb-exchange name=userserve2-84 carp weight=1 cache_peer_domain userserve2-84 userserve.last.fm ###Userserve Ends I had expected to get an equal number of connections spread across each cache_peer instance (we run one perlbal instance per core on each of the machines). What I'm seeing though, is that squid is only connecting to two of the above, and in both cases, the first occurrence of each: [EMAIL PROTECTED] ~]# sort /userservestats | uniq -c 25244 CARP/userserve1-81 25949 CARP/userserve2-81 Does squid, or rather the squid CARP code have something in it which allows it to only use one port per IP address?
