that usually means the webserver is not responding correctly, which
one could interpret as "the server has reached it's limits."  Some
people explicitly define the limit as an error rate. by that I mean
this.

A max of 2% error and response time of Xms

Some people define the limit as the response time for 90% of the requests, as in

90% of the request must be processed within 500ms.

in this case, the process time is the page generation time logged on
the server side. large sites do this, since users may be using a bad
dial-up connection, which means the response time varies wildly.

hope that helps
