I have been seeing a very high cpu usage on my Raspbery Pi: load average: 97.69, 97.60, 97.21

However, I have been closely monitoring htop for a while and cpu usage is around 30-40%. Looks like the culprit is jbd2 when it writes.

Is there a way to see which processes are causing this?

  • load average is not only about CPU load. It could be I/O load. Is your RAM full and the swap space being used? (you can type free in the terminal to check) – foibs Jan 30 '14 at 16:10

  • Check for processes marked as D. – M Noit Jan 31 '14 at 9:28

Yes the output of top will list pids and show the 90+ that are not sleeping. Likely they are all waiting on IO if your CPU is not maxed out.
