Periodic strong brakes on Ubuntu 11.10 (see screenshot)?

Question

ubuntu

Approximately once a day for about 5 minutes.
what is this process, where does it come from, why. And why is this happening.

Answer 1

fuser returns the PID of the processes using the file. (in your case it looks like session files from PHP). I suspect a crooked code or crooked settings, why he needs 200% CPU I can’t explain.
