I am using the latest RabbitMQ java client, but while doing some perf. test
I randomly get this exception:
Caused by: com.rabbitmq.client.ShutdownSignalException: connection error;
reason: {#method<connection.close>(reply-code=503,
reply-text=COMMAND_INVALID - second 'channel.open' seen, class-id=20,
method-id=10), null, ""}
	at com.rabbitmq.client.impl.ChannelN.waitForConfirms(ChannelN.java:182)
	at com.rabbitmq.client.impl.ChannelN.waitForConfirms(ChannelN.java:170)

Why is this happening and how can I workaround it ?
