After roughly 2 or so hours of uptime, Limewire 4.0.4 hangs or fails to refresh the window and doesn't respond to any clicks or tabs or anything and requires me to kill it and reload it to for it to continue running again.

Some details:
Linux distribution: SuSE Linux 9.0
Java: 1.4.2_04
Acting as a supernode at the time with roughly 29 peer connections and 28 to 30 leaf connections.

I've seen it also occur when I was acting only as a leaf with 4 ultrapeer connections.
