Serviio

Again today my cpu was running at 100%, but I was able to stop it from doing so by "stopping" the Serviio "service" in windows 7 and "starting" it again.

Can anyone explain how/why this occurs. Its like a process gets started but does not close. No ffmpeg process shows as active, just the Serviio Console.

No.
Do you check, which process has stuck the cpu (java,etc) ?
Do you have same problem after disabling plugins ?

This is often caused by a plugin, which is not properly coded.

Thanks, I'll check for that.
