Hi,
I have seen a hangup due to full disk /dev/sdb.
the LS script is
- recording from ALSA,
- uses some "say:" generated fallback messages and
- writes the WAV output to disk
- and streams it to the destination via icecast.
The OS and LS is installed at /dev/sda, /dev/sdb was full, which is used for
saving the WAV archive only.
when starting liquidsoap it hang up. LS tries to exit, but the process keeps
hanging in the process tree.
as a result upstart tries to restart it but fail again.

"src_4926" aborts with exception Alsa error: Device or resource busy!
when trying same with pulseaudio it hang up with
/var/log/liquidsoap/play.log 2011/09/06 18:13:05 [threads:1] Thread
"wallclock_pulse" aborts with exception Sys_error("No space left on device")!
I am still wondering why alsa wants to write to /dev/sdb1
Once the wav output target /dev/sdb is full, I would expect an error message,
but should not streaming continuesly run?
