The consolidated and remote databases disagree on when the last synchronization took place. The remote is being asked to send a new upload that starts at the last known synchronization point

Error code 10012
Error constant TXN_LOG_COOKIE_MISMATCH
Probable cause

The MobiLink server stores the remote ending log offsets in its system tables after every synchronization and it compares these ending log offsets with the remote beginning offsets when a new synchronization comes in. If the ending offsets do not match the beginning offsets, the server will show this warning and also inform the client about the mismatching offsets.
