JVM OutofMemory
Hello Everyone,
I am new to this forum. I know there is lot around regarding OutofMemoryException but I wanted to start this new thread. I am a newbie to Java and need help.
My application runs of of Memory at times. I have not been able to see a fixed pattern sometimes its gradual in 1-2 hours sometimes its a sudden drop to 0. These are data from the application log. I am not sure what really is going on in the JVM. I need to know:
1. How can I identify if there is a problem in the application which so what exactly.
2. If not application is the GC not working well and how can I optimize it.
3. If anything else, what can I do to isolate the issue.

Search the net for :java profiler. NetBeans and Eclipse both have one, as well.

Read this, for a start:

Gradually strip out parts of the code and see if the problem disappears.
