But the server disconnects unexpectedly.   This can happen for any number of small TCP interactions. Usually short lived and not repeating.   First thing to do is check that your squid.conf negative_ttl setting is at "0 seconds". If it is higher then it will expand a short temporary error into a full DoS for the length of time it is set to. Being a TCP problem the easiest way to trace this is via the raw packets. If you can find a site and request which always has the problem the packet trace of one such request will show what is happening. Amos -- Please be using   Current Stable Squid 2.7.STABLE9 or 3.1.11   Beta testers wanted for 3.2.0.5
