Artemis 2.5.0 - cluster with UDP multicast descovery - connection
problem
Hello,
I’ve configured Artemis2.5.0 cluster of two nodes with dynamic discovery
using UDP multicast (for load balancing)
I am using simple JMS client based on example from Artemis distribution. It
just sends messages to the queue.
On client side I configured jndi.properties as
java.naming.factory.initial=org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory
connectionFactory.ConnectionFactory=udp://231.7.7.7:9876
queue.queue/EventQueue=EventQueue
When I run the client Artemis works as expected distributing messages for 2
nodes.
But in about 30% of all case application does not run and I get exception
Exception in thread "main" javax.jms.JMSException: Failed to create session
factory

What could be the problem?
Thanks

Thank you Clebert for quick response.
I’ll check my broadcasting.
I’m using UDP discovery on client to avoid configuring any real IP on client
side – it’s a requirement.

you're using UDP discovery on the client. I would check the
Broadcaster on the servers.
Do you really need UDP on the client though? it's usually easier to
connect to a node and get the topology from that node. Say (DNS).
but if you must use UDP, check your configuration. perhaps the
broadcaster is sending an IP the client cannot understand.
