This does not look good....

For some reason things stop in the middle (16:24), until it much later
time out (17:36)..

Possible reasons:

  * Client error, where the client stops accepting the data sent to it
  * A network error, preventing Squid from receiving data from the
server
  * A yet unknown Squid error.

If you can repeat the problem then netstat can be used to tell which of
the above is the case: (all assuming the request is still running but no
data is flowing. If data is currently flowing then any of the three may
be normal)

  - If you see that a lot of data is in Send-Q in the connection from
the client then there is a client error, not accepting the data sent by
Squid.

  - If you see that both Send-Q from Squid to the client and Recv-Q from
the origin server to Squid is empty then the problem is somewhere
between Squid and the origin server, preventing data from being
delivered to Squid.

  - If you see that a lot of data is in Recv-Q to Squid but none in
Send-Q to the client then there is probably a Squid problem.
