Greetings, 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... Jeff Donaldson Technology Director Newark Charter School jeff.donaldson at ncs.k12.de.us (302) 369-2001 ext: 425
My apologies, went to paste and accidentally sent the message...see below for rest of detail.

Can it be you have huge sam.ldb.d/* files with lots of deleted objects? If that is the case, try to upgrade to at least 4.1.11 which includes an fix for the issue. Can you run samba-tool dbcheck --cross-ncs in an reasonable time? Does it report an error for the object with the id ac84ad1f-a645-47db-873f-ccfccd9c621c ? If so you can try to delete the offending object ldbdel -H /var/lib/samba/private/sam.ldb "<GUID=ac84ad1f-a645-47db-873f-ccfccd9c621c >" This is usually not recommended but fixed such an issue on an site I support. So make sure zou have an working backup or an snapshot of the server before you try. Achim
