LISTENER_REREGISTER_CWOBJ1524=CWOBJ1524I: Replica listener {0} must reregister with the primary.
Explanation
The replica will deregister and reregister the primary. It will get a new snapshot of the data and then continue processing new transactions. This could happen if the replica fell behind on transaction processing or if a lost transaction was requested from the primary, but the primary could not resend it.
User response
If this happens frequently, verify that the server can handle the current load. Consider increasing the transaction lag threshold to allow the replica to have more waiting transactions.
