This box is now crashing once every 12 hours.  I can't apply this patch 
:-(.  Does anyone have any suggestions on how I can work around this? 
Some have said its an SMP problem and some have said its a 4 GB RAM 
problem and some have said its an IPF problem .... if I disabled all three 
of those things would that help this box be stable until code could be 
fixed?

Thanks,
Matt
