Squid is attempting to read a reply from some remote server. 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.
