Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

From time to time I see my CPU usage spike and my laptop starts to heat up.

I run top and see that an unrar process is running and consuming anything from 40 - 99% of CPU capacity.

I try to kill it using sudo killall -9 unrar or similar, but the process either respawns straight away or keeps running.

I'm a reformed mac user who's only been running Ubuntu for a year, so sorry I can't provide any more detailed information.

pstree in a console may provide more information as to what is spawning the unrar process, can you add that information to your question? (the relevant bits of it anyway, we don't need it all) –  Caesium Dec 10 '11 at 11:35
    
Thanks for your help, Caesium. The problem hasn't recurred since I wrote this question, so I've no further info on it at present. –  user6942 Dec 23 '11 at 19:06
