My computer has a duel core processor. I am using Ubuntu 10.10. I have a 1 GB RAM. I allocate 2 GB space for swap partition (actually 1 GB is sufficient, but I select 2GB for testing, and I am continuing with this huge space). Normally both of my CPU uses very low process. But for some days (I guess after updating 200 line kernel it occur) I am facing an uncommon problem. I found on system monitor applet and conky that, both of my CPU running about 100%. I am not sure why this happening, but feeling afraid.

I did not run any application when took the pictures below except Firefox:

Both CPU running almost 100% on ubuntu 10.10 a program still running shut down messageWhen I going to shutdown my system, then this dialogue box appear. It is telling that "An Unknown program is still running". So, my ubuntu machine stop shutting down. I have to press "Shut Down Anyway" button.

I don't know why this happen to my Ubuntu 10.10 system. I upgraded 200 lines of kernel patch upgrade with a script. Is my problem casing by it? I applied recent update from ubuntu upgrade. I upgrade Ubuntu systems kernel to 2.6.35.23-generic. But problem exist as same.

  1. I had a similar problem with 10.4 I found that the network manager processes was the culprit. I forced it down and my cpu's went back to normal.
