I'm seeing intensive cpu and hard disk usage on my fedora 20 laptop, resulting in annoying slowdowns.

  • When I open system-monitor there is always one CPU out of four at 100%.
  • top reports 100% cpu time spent in iowait.
  • CPU temperature reaches 70-80 °C
  • In both tools, no process exceeds 5% CPU, occasionally 10-20%.
  • The hard disk led is continuously lit, but iotop reports disk read: 0.0MB/s, disk write: 0.0MB/s
  • I tried to disable swap, but nothing changed.

How can I find responsible processes?


Update 1:

  • dmesg does not report anything strange or bad
  • This happens when I bind mount dev, proc, sys and run in a subdirectory of my home dir. Most active processes (average 5% CPU) are always tracker-store and tracker-miner-fs

Update 2:

  • It happened again right after login, this time without aforementioned bind mounts
  • htop reports tracker-store 98% CPU

I recently had a similar issue on a redhat box, and the trouble was the disk hw. You may check this side.

@fidelleon dmesg says nothing, I forgot to add it to the question

@anishjp I'll check as soon as it happens again

htop allowed me to see that tracker-store was eating 98% CPU time.

Thanks to @anishjp for the tip.

iotop could be used too
