[Icecast] Icecast locks with WARN connection/_accept_connection accept() failed with error 24: Too many open files

[Joel Ebel]

My icecast server has been running happily for months now, but just 
yesterday it locked up, chewing up all the cpu time it could find, and 
not allowing connections.  The last snippet of the error log shows this:

The error had repeated itself for almost 24 hours before I noticed it. 
Obviously it had too many files open, but I can't account for how.  The 
logs before the repeating errors look completely normal.  I tried 
shutting down the streams, which didn't fix it, so I sent it some kills, 
and it didn't die.  I had to kill -9 it.  Once it restarted it was fine. 
  Is there some leak preventing icecast from running indefinitely?  Or 
will I just need to restart it every few months when this happens again? 
  Has anyone else seen this happen?
