Master/Slave Artemis Broker process only 100 messages

I have a set up as below:

Broker A Artemis: on host_1 (master - started first).

Broker B Artemis: on host_2 (slave).

Both brokers are sharing the same journal. So the master/slave setup is made using a shared file system.

In producer, I create a Topic and send 10000 messages. In consumer (which is a listener, extends MessageListener), I receive only 100 messages. After I close Artemis Broker A (the failover is involved), another 100 messages are processed by the consumer.

This behavior should not happen.
