There is a whole thread about javaw.exe taking up too much system resources and crashing.

Basically the conclusion was that if you're sharing a large files, Limewire takes up WAY too much memory and CPU time. This can cause it to crash often. I have Limewire Pro and Win XP Pro and was crashing all the time. I was sharing 2000 files. When I reduced it to 20, it ran as stable as can be and the amount of memory and CPU time it hogged dropped way down.

The Limewire team said they're working on a fix right now and Limewire Pro 2.3.4 should be coming out very soon. I'm hoping this will fix the stability problems.

For now, just don't share as much and hopefully it won't crash on you.

Check out the other thread for more details.
