Hello Henrik, You know I tried it again. and the same thing happened. All the apache processes were waiting for keep alive requests. I am using custom compiled version/removed open ssl since I did not need it. I believe though that I had the same issue with the Fedora rpm. I do have a lot of virtual hosts.
Perhaps this is your problem. I think Squid may maintains the persistent connections independetly per host, even if the ip:port is the same.
Looking.. almost correct. See below.
Here is part of the squid.conf request_timeout 30 seconds persistent_request_timeout 30 seconds server_persistent_connections off httpd_accel_single_host On
This is the root cause to your problems. In this mode Squid gets a bit confused and server-side persistent connections does not work proper as the connection detail does not match the request, making the persistent connections build up and never get reused.
If you like you can file a bug report on this issue, and maybe it will get fixed for 2.5.STABLE12 if there is such release.
http://www.squid-cache.org/bugs/ but there is good workarounds available. See below for details.
httpd_accel_host 127.0.0.1 httpd_accel_port 80 httpd_accel_with_proxy off httpd_accel_uses_host_header on Any thoughts would be helpful.
My recommended vhosting setup works fine without these problems Squid-2.5: httpd_accel_host your.primary.site httpd_accel_port 80 (or 0, if you accelerate multiple ports) httpd_accel_with_proxy on httpd_accel_uses_host_header on acl myservers dst ip.of.real.server ... acl http protocol http acl port80 port 80 http_access allow http port80 myservers http_access deny all /etc/hosts: ip.of.real.server accelerated.domain1 accelerated.domain2 accelerated.domain3 ... In Squid-3 the same config is slightly different and in my eyes simpler: http_port 80 accel vhost defaultsite=your.primary.site cache_peer ip.of.real.server 80 0 no-query originserver name=name.of.real.server acl mysites dstdomain accelerated.domain1 accelerated.domain2 accelerated.domain3 ... acl http protocol http acl port80 port 80 http_access allow http port80 mysites cache_peer_access name.of.real.server allow mysites never_direct allow all Regards Henrik
