Question

channel error; protocol method: #method(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'x-dead-letter-exchange' for queue 'ecpauditchannel.ecpqueue' in vhost 'ecp-audit': received the value 'DLX' of type 'longstr' but current is none, class-id=50, method-id=10)

The following are the configurations set in the properties file.

Answer 1

inequivalent arg 'x-dead-letter-exchange' for queue 'ecpauditchannel.ecpqueue' in vhost 'ecp-audit': received the value 'DLX' of type 'longstr' but current is none, class-id=50, method-id=10)

You can't change queue arguments once a queue is created.

but current is none,

There is no x-dead-letter-exchange argument on the current queue.

auto-bind-dlq=true

Causes this argument to be set.

You have to manually delete the existing queue (e.g. using the management console) to be able to create the new one with DLQ arguments set.
