We have two Windows Server 2012 servers with several different replication groups configured to replicate different folder structures between them. One of these replication groups seems to have a permanent backlog of files stuck in the queue. the "dfsrdiag backlog" command always shows 343 files waiting to replicate in one direction when run at the end of the day. The first 100 files are listed by the command and they are always the same files. When run during the day the dfsrdiag command shows the backlog going up to several thousand (with the same first 100 files listed), but it always returns to 343. There is no backlog in the other direction. All other replication groups set up show no backlogs in either directions. There are no errors or warning in the event logs to say DFS replication has stopped for that particular volume or that the files couldn't be replicated due to sharing violations. I have tried forcing replication and rebooting both servers.
Does anyone have any idea how I can get these files to replicate?
