[Samba] Samba 4 replication causes bind dns to freeze

[Nikos Mitas]

Hello Marc,

yes, samba-tool drs showrepl is working.
at the very begining, on the new dc, samba-tool drs kcc, samba-tool drs kcc
domain1,  domain2, are working.
I have log level = 5 on the new dc, and i can see records replicating
