Hi, Brian and I have been trying to puzzle out a problem we are having related to back end origin server connections initiated by squid. We have squid (2.5.stable1) set up in a reverse proxy configuration pointing at a group of origin servers which mount a number of NFS mounts to serve content from. What we are seeing is that when one of those NFS mount points locks up on the origin server, it will cause a seemingly permanent change to the number of connections and back end refreshes that the squid servers are sending to the origins. Restarting the squid listeners fixes it, but if we do not restart them, the number of connections and refreshes never returns to its normal state. This is true even if the NFS mount point comes back and the origin servers are restarted.
I have seen this go on for over a day, when all of our timeouts are set in minutes and seconds not hours or days. I am curious to know why this behavior exists, and if there is anything that could be done about it? I am asking here rather than the squid user list, because I think it may be something fundamental to the way squid works and not a configuration issue. -- David Nicklay Location: CNN Center - SE0811A Office: 404-827-2698 Cell: 404-545-6218
