Messages are lost in a ActiveMQ network message broker
There are 70 ActiveMQ nodes in a network broker.
There is a single message publisher which publishes messages in to a topic
of primary ActiveMQ node.
The primary node is in the network broker and the messages will flow from
primary node to other nodes(using topic on each node) in a network broker.
The issue is that messages are lost in the network brokers some times
meaning not consistent . we are using ActiveMQ version 5.4.3. What could be
the reason? How can we monitor network broker nodes in real time?
Appreciative your help on this issue.Thanks

Also, if your broker-to-broker network connections are dropping, you'll see
reconnect messages in the broker logs, so you don't need a separate tool to
detect the problem.

5.10.2 and 5.11.1 are the latest versions. 5.10.1 has a memory leak; if
you're upgrading anyway, that's not the one to upgrade to.

Hi artnaseef,
Thanks for the inputs. As you suggested, we will update the ActiveMQ
version to latest 5.10.1.
The topic subscription are non-durable for each broker in the network. Do we
want to configure to durable topic subscriptions? I would need to check the
network connection stability. is there any network monitors, and ActiveMQ
monitor tools so that tool can generate alerts whenever there is some
abnormal conditions happens(in terms of memory, no of messages etc)?
thanks,Reddy.

First off, 5.4.3 is an old version that had many issues; I highly recommend
upgrading.
With that said, Topic flow across a network of brokers is prone to message
loss. For example, if the network connection between two brokers is lost,
then non-durable Topic subscriptions between the two brokers are dropped
until the connection is recreated (just as if end-clients dropped their
connection and similarly lost their Topic subscription). Non-durable topic
subscriptions miss all messages produced to a Topic when the subscription is
not active.
Are the Topic subscriptions all non-durable? Are there any signs of dropped
network connections between brokers?
