After you execute the command to change the queue block size, Replication Server cannot process data that is flowing into Replication Server while the change in queue block size is also being processed.
You cannot change the queue block size of a Replication Server while a subscription is being materialized. If you change the queue block size, and if materialization or dematerialization is in progress, or if the routes are being created or destroyed, the process of changing the queue block size terminates with an error message while Replication Server continues operating.
Once you start the procedure to change the queue block size, Replication Server does not accept another command to change the queue block size until the first change is completed.
Do not use any other procedures to change the queue block size in the RSSD directly, as these procedures may result in inconsistencies in the queue block size configuration and cause Replication Server to shut down.
After the block size has been changed, the queues will be empty.
