The process tomcat {pid 1488.0000 } is leaking handles
We have a server running Peregrine Get Answers which use TOMCAT as part of
its installation
We are seeing (via task manager) a slow build up of handles for the tomcat
app..
Has anyone come across this before?

This "Peregrine Get Answers" application is probably leaking file
handles. Ask their support.

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.
