[RLUG] System freeze

[Sebastian Smith]

Are you using xlockmore or another package to lock your screen, or display 
a screensaver.  I've had issues with opengl-based screen savers (xlock) 
locking my X display when they've run for a long time.

I've also had issues with firefox hogging tons of memory (very 
memory-leakish).  If your using it you should keep an eye on its memory 
useage.
