CPU constantly 50% also pcmanfm constantly respawning.


Hi all!

After a recent update I have noticed that the system is constantly sitting at 50% CPU even when idle! Its knocking the performance of the machine right back when im putting it under simple loads such as internet browsing!

This occured after a recent update. After the update I noticed pcmanfm broke. Fixed it by changing some directory permissions. However i've noticed it is constantly respawing as I can sit and watch the PID increase in number.

Im running arch linux with LXDE and compiz.

Any ideas?

Alex

Ok so I did an update which solved the problem... Till I rebooted.
Top and the LXDE task manager show no processes that are using the CPU, yet overall CPU usage shows as 50%+ (and is 50%+)

Pcmanfm is still constantly respawning.

Ideas?

Thanks

I appear to have solved it!
In the LXDE autostart file i've got pcmanfm starting the desktop prefixed with an @ (if it crashes it respwans).
Due to what I can only assume is a config file error it was crashing and respawning causing the cpu load. So I deleted the ~/.config/pcmanfm directory and completely rebuilt pcmanfm from scratch. This appears to have solved the problem!
