problems with users disconnecting

[paulsen]

Hello there. I'm an admin of a radio called PlanetSide-Radio, and we are experiencing some heavy shoutcast issues.
Our setup is one main 80-user shoutcast server, wich are the first server in our listen.pls file.
The second server connects to the main server as a relayer.
Both servers are running SHOUTcast Distrubuted Network Audio Server/FreeBSD v1.9.4

It looks like both our shoutcasts servers are suddenly just disconnecting lots of listeners, without any errors in the logs.

I cant find anything in the logfiles that would say why, and I cant find any configuration entry that provides more debug'ed loglevel.

This is what basically happends:

<08/23/04@13:43:34> [yp_tch] yp.shoutcast.com touched!


It goes on like this forever. People connect and disconnect all the time, suddenly a burst of disconnects etc.

The server is not losing any packets, I've tested that. And I'm watching the server logs via a SSH window when it happends, so it cant be the connection to the internet.

Any ideas?

There is definately some type of connection issue but it might be on a different "route" to the internet than you're seeing.

Say you have a server in Dallas and you traceroute to it through your ISP, through Level3 and to the provider. You see no issues. On the other end is a listener in LA. They connect from PacBell through Aleron and to your provider. Aleron has a bad router and it's dropping packets between the listener and your server. You don't see the problem but from the listener end you do.

Anytime you see this: [yp_tch] error connecting to yp.shoutcast.com theres a problem because for a full 20 minutes your server was unable to communicate with the YP and probably listeners at the same time.

I would look closely at the provider and do traceroutes from several endpoints from a site like www.traceroute.org (us and overseas) to see where the issue is as you might not be able to see it from your location but can from others.
