javax.jms.JMSException - Wire format negociation timeout - peer did not send his wire format.
If you get exception like this:
javax.jms.JMSException: Wire format negociation timeout: peer did not send his wire format. at org.apache.activemq.util.JMSExceptionSupport.create(JMSExceptionSupport.java:58) at org.apache.activemq.ActiveMQConnection.syncSendPacket(ActiveMQConnection.java:1185) at org.apache.activemq.ActiveMQConnection.ensureConnectionInfoSent(ActiveMQConnection.java:1263) at org.apache.activemq.ActiveMQConnection.start(ActiveMQConnection.java:449)
it can mean one of three things:
You’re connecting to the port not used by ActiveMQ TCP transport
Make sure to check that you’re connecting to the appropriate
You’re using log4j JMS appender and doesn’t filter out ActiveMQ log messages
Be sure to read How do I use log4j JMS appender with ActiveMQ and more importantly to never send ActiveMQ log messages to JMS appender
Your broker is probably under heavy load (or network connection is unreliable), so connection setup cannot be completed in a reasonable time
If you experience sporadic exceptions like this, the best solution is to use failover transport, so that your clients can try connecting again if the first attempt fails. If you’re getting these kind of exceptions more frequently you can also try extending wire format negotiation period (default 10 sec). You can do that by using
wireFormat.maxInactivityDurationInitalDelay property on the connection URL in your client. For example
will use 30 sec timeout.
