Stefan Nilsson updated AMQ-6575:
--------------------------------
Description:
*Issue*
Retained message is not persisted.
*Steps to reproduce*
# Client *c1* connects and publishes a message *m1* to topic *t1* with retain:
*true* and QoS: *2*. Client then disconnects.
# Client connect (with same clientId or different, both works) and *c1*
subscribes to *t1*. *c1* recieves *m1*.
However, if the broker is restarted and *step 2* is re-run, the *m1* is never
recieved.
Shouldn't a retained message with QoS-2 be persisted and send to clients even
after restart?
was:
*Configuration*
Two Linux machines sharing an NFS-export, configured as MasterSlave
configuration with *kahaDB* persistence.
*Scenario*
1. Connecting to an *mqtt+ws* endpoint and publishing a message to topic: *foo*
with retain: *true* and QoS: *2*.
2. Stopping the Master-node (activemq stop) and seeing the previously Slave
takes over.
3. Connecting to the new Master-node (previously Slave) and subscribing to the
topic I sent a retained message to. But no message delivered.
Seems like the retain message is not persisted? Shouldn't this be the case?
Also ran a test when publishing a retain message, waiting for more than 5
minutes and then "fail-over" - no difference.
