Do you have reason to believe that the OutOfMemory exception
is due to:
* some cumulative effect (e.g. memory leak), in which case
you need to restart, preferably (just) before it happens
* the qty of active sessions, so you need to load-balance
when near some threshold (offload to a less busy server
iff poss else "please come back later")
* the complexity of some user's request, in which case your
app isn't really "down" at all...

Tracy,
The JSP does a call to a method in our app -- which if it runs, that means
the app is up and available -- the method does a simple query against the DB
and then returns a status of OK if the method runs through just fine.
In our example from this weekend -- the health.jsp (which is the one that
does this check) ran and returned a good result, but the main
index.jspreturned the 500 error with the OutOfMemory exception. So
that is what is
confusing here.
thanks,
Kim :-)

How is your JSP checking your application? Are you issuing a request to
your app and checking the HTTP status? If so, why isn't it recognizing
the 500? Or is the JSP in your application which is failing?
