Subject RE: ActiveMQ clustered replicatedLevelDB configuration
Date Tue, 12 Apr 2016 19:11:30 GMT
This is a resend of a previous submission with more information.

When I get 3 ActiveMQ servers running in each its own ServiceMIX instance (separate ports
) with Zookeeper structure of 3  to manage them each running from a Java command prompt in
separate folders ( separate ports ).   They form a Master with Slave A  and Slave B.
The activemq.xml and zookeeper config files are attached.
Slave B tries to connect to Master Causing Slave A to disconnect,
then Slave A does a retry connection which causes Slave B to disconnect,
they keep thrashing back-and-forth spitting out exceptions every 2 seconds:

activemq-osgi - 5.10.0 | Using the pure java LevelDB implementation.
activemq-osgi - 5.10.0 | Attaching to master: tcp://localhost:64054
activemq-osgi - 5.10.0 | Slave started
activemq-osgi - 5.10.0 | Attaching... Downloaded 0.00/0.00 kb and 1/1 files

The Master just says this:
activemq-osgi - 5.10.0 | Slave has connected: 0538866c-63a7-459a-a9ee-c1a8c641b6ab
activemq-osgi - 5.10.0 | Slave has connected: 0538866c-63a7-459a-a9ee-c1a8c641b6ab
activemq-osgi - 5.10.0 | Slave has connected: 0538866c-63a7-459a-a9ee-c1a8c641b6ab
activemq-osgi - 5.10.0 | Slave has connected: 0538866c-63a7-459a-a9ee-c1a8c641b6ab


Must be some sort of port contention to the Master?
I assume this is not the way it is supposed to work.
