My apologies, went to paste and accidentally sent the message...see below for rest of detail.


I'm currently experiencing an issue with two of my three Samba servers where one Samba process is pegging the CPU usage and eating up a lot of virtual and resident memory. 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...

Could this just be an issue with re-indexing?
