Hi, you can call the System memory methods to determine the memory used by the VM. If the VM memory drops after the gc your graphics driver software might be the problem.
If the VM memory stays at the high level it seems that your objects are not garbage collected at all. Then you have to check for circular references like shape.getUserData() == object and object.getShape() == shape and release them by clearing the references. With JDK1.3.1_02 and Java1.2.1_03 i cannot monitor memory leaks. I also use the detach meachanism for getting rid of geometry Cheers, Karsten PS: i recently used OptimizeIt to analyse my application concerning memory usage and leaks RWGRAY wrote: > Does anyone have a suggestion/tool for tracking down "memory leaks". > > I build a BracnkGroup with lots of objects.
