[Icecast] ices2 routinely abandons one of its streams

Hi everybody,

I'm in charge of an ices2 setup that's broadcasting a local radio
station on the Net, and I'm currently under fire because one of our
streams has been down twice in two days, forcing me to restart ices2 on
each occasion.  Our client is understandably unhappy about this.

OUR SETUP: I've got ices2 installed on a local machine, broadcasting to
an icecast server across the continent.  (So, yes, connections get
dropped and picked up regularly.)  There are two streams: high-quality
(/cigr.ogg) and low-quality (/cigr-low.ogg).  So far, it's the
high-quality stream that has gone down on both occasions.

WHAT HAPPENS: According to the icecast logs, the connection goes down as
usual; the client eventually resumes the connection, which gets dropped
down again almost immediately for some reason:

<skipping earlier disconnection>
[2004-07-13  13:15:00] INFO connection/_handle_source_request Source logging in at mountpoint "/cigr-low.ogg"
[2004-07-13  13:15:01] INFO connection/_handle_source_request Source logging in at mountpoint "/cigr.ogg"

[2004-07-13  13:15:11] INFO source/source_main Source "/cigr.ogg" exiting

(The icecast log times are in GMT.)

However, the client does *not* notice the latest disconnection:

(The ices2 logs are in EDT.)


netstat shows that the connection lingers in the CLOSE_WAIT state; the
server has closed its end, but the client doesn't pick it up.

tcpdump doesn't show any traffic on what remains of the connection, so
the client doesn't appear to be broadcasting.  Yet it's not closing the
connection either.

I'm attaching ices2's config file.  Any help or pointers would be
appreciated; otherwise I'll have to sprinkle some fprintfs everywhere
and hope for the best. :(
