------- Additional Comments From trawick@apache.org  2005-04-05 13:30 -------
Assume that it is requests to the application server which have hung, and
consult vendor to determine how to diagnose (e.g., take java cores of app server
to see why the application(s) isn't (aren't) responding.

Verify this by monitoring server-status up until the point where it runs out of
threads, and check for an increasing number of requests which are stalled.

Another possible way to verify that the hang is with applications running in the
app server is by using netstat to monitor the number of established connections
between Apache and the application server.  If the number is at or very near
ThreadsPerChild when Apache can't accept new connections, then, as mentioned
before, see what is going on in the app server.

If the server-status reports indicate that it is some native Apache request
which is stalling (e.g., static file), reopen the PR, as perhaps there is
something we can do to help.
