DFS / NTFRS Error - 13506.

File Replication Service (FRS) Event ID 13506 and ID 13555
An assert may occur when a local create change order (CO) is sent to an outbound partner. In this case, not all outbound partners are available, and therefore the staging file remains in the staging table. This outbound member is later removed and re-added to the replica set. At this time, it receives the same CO from its inbound partner. This new member has a new originator globally unique identifier (GUID), and therefore the CO is not dampened. This CO is treated as a remote CO, but because it was already in the staging table, it is picked up with the old flags. The following events are logged when this error occurs:
Event ID: 13506

Recovery Steps:
[1] The error state may clear itself if you stop and restart the FRS service. This can be done by performing the following in a command window:
net stop ntfrs
net start ntfrs

I don't think either of those refer precisely to the error listed here. (CMD_PKT_WAIT_FLAGS_ONLIST))
in "FrsFreeType:" at line 2534. )

It also doesnt suggest any methods to take to resolve the issue?

Anyone have any ideas?

Please note (to my horror) we do not have a working system state backup :(
