Clustering not working...

[LouR]

Might anyone know what might cause this?

After months of streaming and relaying flawlessly, the main server starts getting "service full, disconnecting", and thus doesn't relay?

This started happening about 2 or 3 days ago. I have the 5 tomcat (YP) IP numbers on the reserve list (unless there are others that I don't have the IP numbers to - if so would others care to share?).

I am also getting this NAK error:
<01/01/15@12:48:23> [yp_add] yp.shoutcast.com gave error (nak)
<01/01/15@12:48:23> [yp_add] yp.shoutcast.com gave extended error (Internal error - unable to acquire data source)

Never seen it before.

Wondered if anyone else has encountered this and what, if any fix you may have had.

Thanks
