BIP4236
Severity
30 : Severe errorMessage
Node '<insert_0>' failed to bind to port <insert_1>Explanation
The port number specified for the node is already being used in another message flow, or is unavailable for some other reason.Response
Change the port number to one not being used by another message flow or by another quite separate application. If one message flow is replacing another using the same port number, use a full rather than a delta deploy. This ensures that the old flow is removed from service at the broker before the new flow is introduced.
