Can someone help me out with this.<br><br>I've been using RabbitMQ locally on my windows box successfully for sometime. But when I try to run on linux with server and client on different linux machines I get this error<br><br>AMQP protocol version mismatch; we are version 0-9-1, server sent signature 1,1,0,9<br><br>I am using RabbitMQ version 2.5.1 server and client which supports 0-9-1 but I dont know why the server signature says 1,1,0,9.<br><br>To narrow down the problem the java client build I'm running I first ran on Windows and pointed the host to the Linux Rabbit server. And it worked fined when I passed some messages.<br><br>But using the same client build deployed on a Linux box I get the above error. Only when it tries to send a message not on startup. Here is the exact stacktrace<br><br>Exception in thread "pub-sub-pool-2" org.springframework.amqp.AmqpIOException: java.io.IOException<br> at org.springframework.amqp.rabbit.connection.RabbitUtils.convertRabbitAccessException(RabbitUtils.java:109)<br> at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.createBareConnection(AbstractConnectionFactory.java:118)<br> at org.springframework.amqp.rabbit.connection.CachingConnectionFactory.createConnection(CachingConnectionFactory.java:179)<br> at org.springframework.amqp.rabbit.connection.ConnectionFactoryUtils$1.createConnection(ConnectionFactoryUtils.java:77)<br> at org.springframework.amqp.rabbit.connection.ConnectionFactoryUtils.doGetTransactionalResourceHolder(ConnectionFactoryUtils.java:121)<br> at org.springframework.amqp.rabbit.connection.ConnectionFactoryUtils.getTransactionalResourceHolder(ConnectionFactoryUtils.java:67)<br> at org.springframework.amqp.rabbit.connection.RabbitAccessor.getTransactionalResourceHolder(RabbitAccessor.java:100)<br> at org.springframework.amqp.rabbit.core.RabbitTemplate.execute(RabbitTemplate.java:402)<br> at org.springframework.amqp.rabbit.core.RabbitTemplate.send(RabbitTemplate.java:225)<br> at org.springframework.amqp.rabbit.core.RabbitTemplate.convertAndSend(RabbitTemplate.java:242)<br> at org.springframework.amqp.rabbit.core.RabbitTemplate.convertAndSend(RabbitTemplate.java:238)<br> at com.comp.transports.fix.handlers.Sender$1.run(Sender.java:115)<br> at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)<br> at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)<br> at java.lang.Thread.run(Thread.java:619)<br>Caused by: java.io.IOException<br> at com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:107)<br> at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:261)<br> at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:403)<br> at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:423)<br> at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.createBareConnection(AbstractConnectionFactory.java:116)<br> ... 13 more<br>Caused by: com.rabbitmq.client.ShutdownSignalException: connection error; reason: com.rabbitmq.client.MalformedFrameException: AMQP protocol version mismatch; we are version 0-9-1, server sent signature 1,1,0,9<br> at com.rabbitmq.utility.ValueOrException.getValue(ValueOrException.java:67)<br> at com.rabbitmq.utility.BlockingValueOrException.uninterruptibleGetValue(BlockingValueOrException.java:33)<br> at com.rabbitmq.client.impl.AMQChannel$BlockingRpcContinuation.getReply(AMQChannel.java:328)<br> at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:246)<br> ... 16 more<br>Caused by: com.rabbitmq.client.MalformedFrameException: AMQP protocol version mismatch; we are version 0-9-1, server sent signature 1,1,0,9<br> at com.rabbitmq.client.impl.Frame.protocolVersionMismatch(Frame.java:183)<br> at com.rabbitmq.client.impl.Frame.readFrom(Frame.java:120)<br> at com.rabbitmq.client.impl.SocketFrameHandler.readFrame(SocketFrameHandler.java:140)<br> at com.rabbitmq.client.impl.AMQConnection.readFrame(AMQConnection.java:397)<br> at com.rabbitmq.client.impl.AMQConnection$MainLoop.run(AMQConnection.java:425)<br><br>Thanks,<br>Cory<br><br><br> </div></body>
