[SOLVED] Skype using 100% CPU

mauritzius · 2012-07-17 16:43:44

Some days ago, Skype started using >100% CPU.
I tried downgrading to 2.2 and to delete my .Skype directory as well as disabling Pulseaudio - same problem persists. There is no output if I start Skype in a terminal.

I'm on 64bit Arch, Multilib, stable repos and using Pulseaudio. On another machine with a similar configuration there is no problem.

Anyone experiencing similar problems? Or does anybody have solution?

Thanks

did you remove the cache folder for it as well?

Contact microsoft support. Bonus point if you provide them strace output.

Which cache folder? Is there anything outside .Skype?

Might be in /tmp/.cache or something similar.

try

pacman -R skype
then
find / -name="cache"
or 
find / -name="skype"

delete all of them related to skype

pacman -Sc && pacman -S skype

or at least that is what I would try.

Thanks for your reply, I tried your suggestions. Unfortunately, it didn't help, I'm still stuck with a Skype using 100% CPU.

In the meantime I had a look at the process table using htop and it seems that Skype is launching around 10 subprocesses of which one keeps running and goes crazy.

Solved - finally!
The subprocess which went crazy was called "FallbackConnMan" and using strace -ff I finally found the cause: I had a symbolic link cycle inside my Mozilla profile - for whatever reason Skype is looking in there! It tried to read /home/USERNAME/.mozilla/USERNAME-mozilla/USERNAME-mozilla/USERNAME-mozilla/... and so on and got into an endless loop. After removing the link, Skype behaves normally again.

I do have the same problem with the new skype version. Old 2.x(2?) worked absolutely fine!

strace outputs so much for me and i dont know how to filter it / understand it. Could you explain a little more what you did?
