Well, besides the other posters' response about the cache peer setup being a clue - you're choosing a peer based on source IP as far as I can tell there - which leads me to think that perhaps that particular cache has a problem. You didn't say which caches they were in your config or error message so we can't check whether they're the same or different. But since yo'ure using a supported squid for RHEL5.3, why don't you contact Redhat for support? That is why you're paying them for. adrian
