[icecast] Runaway icecast again (more YP issues)

[oddsock]

a couple things here....in most cases the icecast2 server will remove 
itself gracefully from the YP...if for some reason, it is killed manually, 
then it may not do so...I have a cron job which runs every 5 minutes which 
goes in and cleans out any server that hasn't touched in a 5 minute 
period....so if your icecast2 server is forced down and doesn't 
successfully remove itself from the YP,. then for the next 5 minutes or so 
you should see the error message (Server already exists) with the NAK (as 
you see in your log)...Eventually, the clean script will run and will clean 
up your stale entry and icecast2 is configured to keep trying to do the 
yp-add until it's successful...so after about 5 minutes of NAKs, you should 
then be able to list again.

o thats the way it's supposed to work, and I just checked the DB, and 
there are no stale entries, so you shouldn't be getting the "Server already 
exists" message anymore, although clearly, according to your logs, you 
are...so can you send me the Server NAme you are using (this is specified 
in the source client) ?  Feel free to send me the info to 
oddsock at oddsock.org...
