Yeah, I've noticed a general wonkiness of RHAS 4 and derivative distros 
( both CentOS and WBEL). 

At home, I have a CentOS 4.2 machine on x86_64.  After a while of 
running, I always seem to have a problem with X no longer accepting 
connections...it's like $DISPLAY gets whacked but I can't make it right 
which an environment variable change or an xhost command or anything. 

At work, I have RHES 4 on a IBM HS20 blade and periodically it is 
sloooooowwwww, even with 4GB of RAM.  I'm running Apache for internal 
use and a few other small things, and that's it.  At first I thought it 
was hardware failure but I've run full diags on the machine and so has 
my other admin, and it comes up fine.  But lately it's needed a reboot 
every now and again to stay sane.....not something I'm keen on as a 
Linux admin.

I installed WBEL4 on a friend's machines and after I fixed the little 
things (like the bad repos in yum, etc.), he still has a similar problem 
to mine with X....something whacky happens and he'll no longer be able 
to initiate new programs that use X, although the ones he has open work 
fine.  Again, resetting $DISPLAY doesn't seem to fix the problem.

I haven't been able to figure out a pattern to the X failures.  Intially 
I thought it might have been related to me firing up a vnc server every 
now and again, but that doesn't seem to be the case. 

For my ~250+ machines at work, I'm sticking with WBEL3 for the meantime.
