While this is happening I get a "ERROR(runtime): DsReplicaGetInfo of type 0 failed - (-1073610723, 'NT_STATUS_RPC_PROTOCOL_ERROR')" error when I try to run the samba-tool drs showrepl command. When that singular process drops (albeit temporarily) I can get the samba-tool command to complete. It shows everything is replicating successfully. This is happening on both of my Samba 4.1.9 servers. One is Ubuntu Server 12.04 and the other is Ubuntu Server 14.04. It seems to be pegged more on the 12.04 box though. I'm also seeing these errors in 12.04 log.samba...

What does an strace log say ?
