[Icecast] EROR connection/wait_for_serversock signalfd descriptor became invalid

[Michael Smith]

Hi Rob,

You're not using icecast; you're using the "KH" icecast fork. This is
a considerably different codebase. Mostly, it adds a few features, and
is less well tested/less stable.

>From the code you quoted, this is clearly a hacky workaround for a
bug. I would recommend upgrading to the latest release of standard
icecast.

Mike
