Memory leak

Hi everyone

I'm developing a web application using flash and I'm getting some sort of memory leak. Every time I load one of my pages, the JBoss process (named Java, in the windows task manager) grows 3MB and this memory is never released.

I want to know what is the default behaviour of JBoss concerning memory handling. Is there some allocation limit - something like "if it gets up to ***MBs, runs a garbage collector"? And is there a way of configuring the memory handling - set a lower limit, or release the memory of a page at the same time the browser changes the displayed page?

And also, I'm a JBoss newbie, and this memory leak may not be related to JBoss. If that is the case, is there somebody here that has faced the same problem? Have you solve it? How?

Thanks in advance for your attention

Observing memory usage in Task Manager is not an accurate measure of how a Java app is using memory. The memory Task Manager reports includes both the memory that the JVM uses to do its job and the heap space used (the Java app's data).

The default settings for the heap in run.bat allow for the JVM to continually ask for more memory for the heap, up to 512MB.

To better understand how the Java heap works, including garbage collection, see my presentation at http://www.cecmg.de/doc/tagung_2007/agenda07/24-mai/2b3-peter-johnson/index.html
