I can't say anything about your log, but I am using polling and it works well.  All I did was add my server name to the client.conf file:

Servername server.domain.com

, and restart CUPS.  The rest was automatic.  within a microsecond, I could see all my servers printers, lpstat.cups -a ,

It worked much better then broadcasting because of the routers/bridges etc..
