I have a memory leak with Glassfish 3.0.1 and Windows Server 2008 R2 Enterprise (64bit machine), with or without any running applications
Is there a way to resolve this?
The same Glassfish 3.0.1 work fine on linux and Windows XP SP2 without any leaks.
I can see the leak through the Windows Task Manager. I am using Java SE 6 update 22
Thanks!
Answer
The best way to identify memory leaks in Java is to start up the server and let it get warmed up to a normal operating level and then take heap dumps over time. If you are using the Sun JDK you can trigger a heap dump like this:
jmap -dump:file=normal.hprof <pid of java process>
Let the server run for a while and when you see the memory start to climb take another heap dump.
Repeat this process as the heap grows until you are satisfied that you have a good set of data.
You can use jhat to analyze the heap dumps to see what types of objects are filling the heap. The culprit(s) will be increasing over time.
