I use a macbook pro (the earlier silver version) with OSX 10.5.8 as my work computer. Today I started noticing that the machine will randomly spike CPU and bandwidth to 100% ever 10-15minutes (I use iStat Menus to monitor this), with the spike lasting about 2-5 minutes each. During this time the machine is sluggish and I can't get to any websites. If I disconnect the ethernet cord during a spike (not using wireless), both the CPU usage and bandwidth usage go to background levels. As soon as I plug back in however they continue to spike.
Activity monitor shows that kernal_task and natd are using the CPU at 75-95% each during the spikes.
Does anyone have any idea what might be causing this or how I can stop it? I haven't installed anything recently and there are no programs launching during startup that I can tell.
Thanks for the help!
