[Samba] Replication issues after OS upgrade

[George]

I'm using the internal DNS backend from Samba.

Anyway, after some further research, I found this:

https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1357471
https://bugzilla.samba.org/show_bug.cgi?id=11164

Not sure if the patch included is just a cosmetic one to avoid the error
message or indeed fixes the replication problems.
I can confirm this is due to connectivity issues between the DCs, as stated
in the Ubuntu bug. In my case it occurs at the same time that our routers
renegotiate the VPN link over a different WAN link. Once the connectivity
is restored (which is almost inmediately, BTW) replication does not recover
unless samba is restarted.

I guess I will apply the supplied patch, try again and report back. It
still puzzles me why this never occurred on Debian Wheezy with the same
Samba version and network conditions.

Best regards
