The swapRunnable and run methods clearly point to Thread execution in JRUN.
My guess is that you have a thread conflict, or possible a "race" condition
between two execution threads, which is causing your product to "lock-up"
while waiting for one of the threads to complete execution. Without seeing
your code I am making a total guess, but is your servlet code designed to be
multi-threaded, or did you design it to be single threading only? If it is
designed to be multi-threaded, did you synchronize the methods in your
servelet class that require synchronization. Also, if your servlet is
accessing your db, are you using a driver that can implement connection
pooling (i.e. pull a connection thread out of the connection pool), and if
so, did you select the connection pooling checkbox in the JRUN JDBC console?
Those are just a few educated guesses as to the things I would look into
without knowing more about your servlet code.
Hope this helps!!!

Subject: what is "Exception while swapping" ?
In an attempt to debug what appears to be a lockup we turned debug on in
logging. One thing we see is this:
--
08/07 16:04:43 info (JRun) f_req_drw_Servlet.doGet END
08/07 16:05:00 debug (web) web-480 caught Exception while swapping
[java.lang.InterruptedException]
java.lang.InterruptedException
at allaire.jrun.http.WebService.swapRunnable(WebService.java:118)
at allaire.jrun.ThreadPool.swapRunnable(ThreadPool.java:223)
at allaire.jrun.WorkerThread.run(WorkerThread.java:77)
08/07 16:05:10 debug (web) Limiting InputStream read to '-2' bytes to
maintain keepalive.
08/07 16:05:10 info (JRun) f_req_drw_Servlet.doPost BEGIN
--
The END / BEGIN info's signify our code appears fine. Can someone clue
me in on what this might mean? Thanks, BenG.
