Without access to logs and debugging you really can't tell anything about where the problem is likely to be.

For instance one that I was part of trying to track down was finally tracked down last week to Linux machines being set to try to communicate at 10 or 100 on an ethernet, while the Cisco router was set to 100. Most of the time it worked, but occasionally it messed up, causing a dropped connection and a socket hanging for 5 minutes (which is what Apache's timeout was set to). Configure the Linux machines to only try to talk at speed 100 and the network problem went away. Would you have ever thought of that?

I wouldn't have. The person who figured it out started in the system logs and noticed a lot of TCP/IP errors, then went from there...
