Hi,

Today I had a problem with my multi server setup. I have dnssec domains that get resigned every month by DA. The problem is sometimes pushing out the changes to the other server(s) fails. But DA does not try again to propagate the changes to the other servers. It just fails and leaves it.

It would be better for the multi server tool to check zone serial from time to time and when it finds a server with a mismatch update it to the most recent serial (by pushing it own or pulling from the other server, depending on who has the most recent one).

Because atm it stays under the radar until certain software stops connecting because the dnssec signatures are no longer valid..
