[CR #468408] When upgrading from Replication Server 12.6 32-bit to Replication Server 15.2 64-bit, the 64-bit server cannot read the queue data in the 32-bit server.
Workaround: After upgrading, rebuild the stable queues and ignore loss for all connections. Run:
rebuild queues
ignore loss from <pds name>.<pdb name> to <rds name>.<rdb name>
