6674 RSG work queue storage exhausted.
The internal storage structures that are used by the RSG to enqueue transactions that are ready to be sent to the intermediary has reached its capacity. This condition can occur when the replication intermediary has disconnected from the RSG, causing a transmission backlog to accumulate. When this condition occurs, transactions that are awaiting transmission of their data to the replication intermediary may be aborted.
System administrator or end user
Insure that the intermediary (replication transport subsystem) is operational and then rerun the failed transaction.
