Just in case anyone is running RH's latest updated kernel,
I just noticed that it's kswapd is running at near MAX CPU usage
on my just-installed RH 7.2 machine.
I'm running about 10Mbps of ethernet traffic on the machine, and
a Java GUI and not much else.
I guess once again I'll be shipping a bleeding-edge hand-built
kernel :P

Well, I did notice that the rawhide kernel is now at 2.4.16 -
Who knows, it might be worth a shot...
