I do see that after letting LimeWire run for several hours that sometimes MacOS X 10.1.3 locks up solid, the mouse moves but nothing reacts to any mouse click. I can not even ping the MacOS X box from my other computers anymore. The last thing I see is that the CPU meter does display a fully loaded CPU, with system load about at 50% and the rest is user load, no idle state. I do share some 600 files (4GB). Does anybody else see this or is my machine special?
