Hi, I have a squid with some parents. Suddenly I'm habb 2009/09/25 16:09:03| TCP connection to 10.10.50.233/3228 failed 2009/09/25 16:09:03| TCP connection to 10.10.50.234/3228 failed 2009/09/25 16:09:03| TCP connection to 10.10.50.235/3228 failed My conf related: cache_peer 127.0.0.1 parent 3228 7 login=*:nopass weight=95 name=dg1 no-netdb-exchange no-digest no-query default cache_peer 10.10.50.232 parent 3228 7 login=*:nopass weight=1 name=dg2 no-netdb-exchange no-digest no-query cache_peer 10.10.50.233 parent 3228 7 login=*:nopass weight=1 name=dg3 no-netdb-exchange no-digest no-query cache_peer 10.10.50.234 parent 3228 7 login=*:nopass weight=1 name=dg4 no-netdb-exchange no-digest no-query cache_peer 10.10.50.235 parent 3228 7 login=*:nopass weight=1 name=dg5 no-netdb-exchange no-digest no-query I wonder to know why does this happens, is there a way to tell squid persistent connexions?
