I've been sitting here for the last 10 minutes or so with Limewire 4.0.8 running under OS X 10.3.5 with the latest Java update installed.

I've watched in Activity Monitor as the "Real Memory" value has increased from about 95Mb at launch to 116.5 at the moment.

I first noticed this when my system was reacting slowly and I found 5 swap files were created on a machine with 1.5GB of RAM. When I looked at the process list LW was consuming 684MB of Real Memory and had reserved over 1GB of virtual memory.

In just the time I've been typing now the Real Memory usage has climbed to 117.07 MB.
