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 at org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory.createConnectionInternal(ActiveMQConnectionFactory.java:815) at org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory.createConnection(ActiveMQConnectionFactory.java:277) at org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory.createConnection(ActiveMQConnectionFactory.java:272) at org.apache.activemq.artemis.jms.example.ScheduledMessageExample.main(ScheduledMessageExample.java:117) Caused by: ActiveMQNotConnectedException[errorType=NOT_CONNECTED message=AMQ119007: Cannot connect to server(s).
