Subject: How to clear CPU congestion?
.
I asked this question a while ago and never did get a solution,
so thought I would try again. My system normally runs with a
very small number appearing for "X" under %CPU ... but sometimes
something happenss that causes it to jump to a high number (as
shown below) and the only way I have found to clear it is to
reboot. Then it runs fine for quite a while until the same
problem occurs again. Surely there must be some way to clear out
whatever is causing this log jam other than reboot.

Any suggestions?
