[Pdns-users] Domain is stale, not updating zone, running in loop

[TWC|Mario Peschel]

Hello,

I was running PowerDNS for months without problems. I have to servers, 
one is the primary dns (and supermaster) and the other is the secondary 
dns. Both running PowerDNS with mySQL backend.

Usaly, when something on the primary dns is changed, it will notify the 
secondary. This still works. Then the secondary will get the zone data 
from the primary. But this does'nt work anymore since some days. I tried 
to delete the zone from the secondary and download a fresh from the 
primary but this doesnt work too.

The logfile doesnt show anything important to me:

This is going on endless in a loop.

The PowerDNS webinterface on the primary under the 'Top 10 Remote server 
IP-addresses' shows my secondary with 98% and 5000 hits.

What is going wrong here? How can I get more debug infos? :-(

Thanks,
Mario
