I have a couple of Icecast servers at Digital Ocean used as a relay to our main Icecast server at AWS. For some reason the edge server (the one receiving connections from end users) hangs completely.

I had to setup Supervisord to do an HTTP request to status.xsl to determine if it's up, so it can be restarted when it happens (status.xsl request times out). Actually this happens both servers, same behavior hanging every 1 or 2 days or so.

This is not a busy streaming server (about 400 listeners peak each). When it hangs sometimes it's not on peak hours, I've seen it happening early morning.

Error_log stops longing when it happens, so there's not much information there (using loglevel 3).

This icecast server is running in a docker container, just like the main server. I'm starting this docker image with ulimit 1024:1024 for nofile.

How can I provide you with more info so we can see if this is a bug?
