[Samba] Samba 4 replication causes bind dns to freeze

Hello,

Joined a new samba 4 dc to an existing pair of samba 4 domain controllers,
but i have a problem with replication.

5-10 minutes after starting samba services on the new samba 4 server,
both   dns servers on the old Domain controllers freeze.  Nothing works.

all i can do is to kill all the services (ntp,named,samba) and start over
again.

i get this message  on new dc in this file: /usr/local/samba/var/log.samba:
....
dreplsrv_notify: Failed to send DsReplicaSync to
4d2038d4-3b1c-41a8-9865-142f7e9cadba._msdcs.example.com for
DC=example,DC=com - NT_STATUS_IO_TIMEOUT : WERR_SEM_TIMEOUT
.....
environment:
Redhat 6.5
Bind with dlz v9.9.5

Thanks for your help
