[Pdns-users] Weird problem

[Hans Christian Saustrup]

Hi!

I'm running three nameservers, and I'm currently in the process of 
moving two of them from one IP segment to another. The primary 
nameserver was no problem, but my slaves are behaving strangely and 
replying with both correct and "stale" A-records, eventhough the AXFR 
looks fine.  Version is 2.9.18 compiled from source. Backend is MySQL. 
Serial is the same on both servers, and both were restarted several 
times after the update, just to make sure pdns wasn't cashing anything.

Any input you might have is highly appreciated.

Cheers,
HC

Primary nameserver: everything ok:
