Problems with consumes a lot of system resources

[Eric]

I have a multithreaded java application which on running more than a day creates a huge number of threads in the system and consumes a lot of system resources than expected.
Application uses java1.5 and runs on Windows2003 server.

Any ideas? Thanks.

Does it create Java threads or are these Windows O/S threads? Java can handle having thousands of threads and Windows handles it ok too. But it would help to know a bit more about the application. What does it do?

Is it something you have the source to? If so you may want to use a tool to do some instrumentation on the code to see where the resources are being used.

I have the source of the application.
Jobs are submitted to my application through a client with a pre-defined input rate.My application processes the jobs ,throws the desired output as requested by user.

I feel the problem is in my application rather than submission rate of client.
Previously my application was working fine,after a few bug fixes in my application this problem is see.Not able to narrow down where or which fix caused the application to behave like this.
Ready to give further info if required.

Greetings.
