Hello!
After more testing I think this problem may be a communication issue between
certain encoders and liquidsoap. I'm not sure what the exact problem is, but
the buffer death-spiral appears to be consistent while streaming with the
Shoutcast encoders in Edcast, Oddcast and Station Playlist. I believe they
all share a code base.
There also appears to be a problem with liquidsoap switching between the
input harbor and a local source when using these encoders. It was sporadic
and I couldn't reproduce it predictably.
