Finding memory leaks.

Hey
I have memory leaks in a very large program. Can anyone suggest a decent profiling tool which I can use to spot them?
Thanks

What language ?
The below is based on my experience, with an extremely large c++ application.

Rational / IBM Puirfy is excellent at this. Unlike some other tools it does not require wholesale changes to the source code. This is commerical. but not too costly.

Under i386 linux valgrind seemed to be okay.

Thanks for the reply.

It's written in Java and unfortunately I am not able to spend any money. Any ideas?

Hi Kevo,

JProfiler is good at this although I've heard that YourKit is better.

You can get trial licenses for both.

Good luck.

Could try jvmstat from sun.

It also comes as a module that can be integrated with Netbeans IDE.

JProfiler is quite good, you can download a 10 day evaluation version. Also if you are using Eclipse as your IDE it will install the necessary plugins for you.

Also if you have any SWT widgets in your application you can use SLEAK for checking for widgets not disposed of.
