PowerMac G4 MDD

I noticed that my fans on my PowerMac G5 are running a little more than usual while my computer is pretty idle/has very few applications open. I then noticed that the graphs of my CPU usage in iStat go up and down like the spikes on the back of a stegosaurus. I have it pictured here, and sometimes it's more defined... I am wondering why the heck this "SystemUIServer" keeps going in and out of using like 7+% of my CPU and 2% of the CPU. Then there is this other thing I am seeing now called "WindowServer", and that has been spiking around as well. Normally my computer's CPUs barely have any activity at a moderate/idle stat, but that has changed. Anyone know why? I am not running 3rd party Dashboard widgets, and the only foreign thing on my toolbar is iStat menus, which I haven't had issues with before. Any ideas? Thanks!

P.S. Come to think of it, "WindowServer" is beginning to be the largest culprit here, next to "SystemUIServer"!

iStat Menus 2 has a memory leak. Periodically you will want to kill the SystemUIServer process because of this.

Open up terminal and type:
killall SystemUIServer

Your menubar will close then restart. The CPU will return to normal.

You can minimize future problems by not using the clock in iStat Menus.

I did kill it off and I think by now it's okay. I was thinking it would be something of that sort. Thanks for the info, and I didn't know that the clock would be something to kill off. I will go ahead and do that if it's indeed still up there. The date is wrong on it anyway for some reason. xD
