Hi List,
I have a problem with liquidsoap. After about 2 or 3 days of streaming (only
local mp3 files from playlist) liquidsoap stops sending data to Shoutcast and
Icecast Servers. I recently compild liquidsoap from source. Here are the last
log lines before liquidsoap "crashes":

The process itself is still alive consuming 15-20% CPU. The (virtual) server
runs Ubuntu 14.04 LTS. I'm not using the binary version provided by Ubuntu
because smart_crossfade only works once in this version.

b >= a + margin and a <= medium and b <= high
then

Are there any known problems?
Thanks.
