I think, I'm not quite getting it:
You (your organisation) bought Get Answers and Tomcat is used as a
part of it. I.e. Tomcat can be considered as part of Get Answers. Right?
Then Peregrine has the responsibility to fix any errors which occur in
this combination.

Re: The process tomcat {pid 1488.0000 } is leaking handles
I could think of quite a number of reasons, why handle are leaked.
Without further knowing the application I could only guess.
Since Tomcat is widely used and I haven't heard of handles leaked by
tomcat (itself) here on the list, I would strongly suspect the Get
Answers application as the source of the problem.
Most of the time not tomcat is the problem, but the web-application
deployed to tomcat.

Since this has not been reported by anyone else, it is highly likely to
be the application, not Tomcat. In any event, what version of Tomcat,
what OS, what JDK, etc., are you using?
On task manager it does indicate that tomcat is at fault..
That's only because all applications under Tomcat are part of the Tomcat
process.

RE: The process tomcat {pid 1488.0000 } is leaking handles
I have a web application that I host for our customers. Right now we are
running about 60 virtual hosts with tens of thousands of hits per day. I've
also run stress tests using Jmeter where literally millions of requests are
generated. I have never observed a resource leak.
This is a common topic in the forum. In almost every instance, it is the
application that is leaking resources.
Developers should run findbugs:
http://findbugs.sourceforge.net/
And PMD
http://pmd.sourceforge.net
To scan their applications for resource leaks.

All task manager can tell you is that the application
Tomcat is holding all these file handles opened. Your
application is running inside of Tomcat, so of course
the tomcat application is holding the files open, but
if your web app is doing this then it's the code in
the web app even though the Tomcat server is holding
open the files. The code opening the files should be
closing them. What files are being held open? Can
you tell this with any tools you have? That would
help you more than anything.

Another suggestion. Grab a copy of JBoss or Sun App Serv (or whatever you have handy) and see if the problem is reproduceable on one of those platforms. If so, the problem is clearly with the app, not the app server.
