Hello,

I am using the most recent stable icecast (2.4.3) with the following config: https://gist.github.com/mspanc/5e560e8fbd07bf65bc30a288cb514c14

From time to time, CPU usage hits 100% and keeps on that level once it’s hit. According to htop, only 20-25% is a regular usage (green bar on htop), rest are kernel threads (red bar on htop).  

Am I doing some relaying and fallbacks as you can see in the config.

*-silence mounts are streams that just play silence and they are synced to the clock.

Is there something that is prohibited by the architecture of icecast or is it rather a bug?

Thanks,

Marcin
