William Blackburn commented on AMQ-1079:
----------------------------------------
Please, ActiveMQ developers, please comment on this issue - it is a showstopper
for us. Even the knowledge that you are unable to reproduce would be helpful,
because we could then provide more data or test-cases. Our story is as follows:
We configure the master and slave according to the instructions on the site.
They both start up OK, and we can see from the logs that the slave attaches to
the master. But, as soon as the first connection is made to the master, the
slave dies. When the client attempts to failover, the slave can't accept the
connection of course, and everything fails.
The master log looks like:
INFO DefaultDatabaseLocker - Attempting to acquire the exclusive lock
to become the Master broker
INFO DefaultDatabaseLocker - Becoming the master on dataSource:
