Subject: [PATCH] Ticket 49380 - Crash when adding invalid replication 
6405db
 agreement
6405db
6405db
    Bug Description:  If you add a replication agreement with an invalid "replicaEnabled" value
6405db
                      the server crashes when freeing the replica schedule.  This is because the
6405db
                      schedule never gets allocated before the rror conidtion is hit, and then
6405db
                      it get dereferenced.
6405db
6405db
    Fix Description:  Check for a NULL schedule before trying to destroy it.
