[Opendnssec-user] zone serial has gone backwards

[Volker Janzen]

Hi,

after some time I made an update to one of my signed zones today, 
resulting in this log entry:

Jul 16 08:51:41 a named[14367]: zone EXAMPLE.COM/IN: zone serial 
(1405493501/2960748158) has gone backwards

How can this happen and how can I fix this? The slave DNS servers are 
not picking up the new zonefile.


Greetings,
   Volker
