Internal - Low level protocol description
Indicates that the method completed successfully. This reply code is reserved for future use - the current protocol design does not use positive confirmation and reply codes are sent only in case of an error.
The client attempted to transfer content larger than the server could accept at the present time. The client may retry at a later time.
Returned when RabbitMQ sends back with 'basic.return' when a 'mandatory' message cannot be delivered to any queue.
When the exchange cannot deliver to a consumer when the immediate flag is set. As a result of pending data on the queue or the absence of any consumers of the queue.
An operator intervened to close the connection for some reason. The client may retry at some later date.
The client attempted to work with a server entity to which it has no access due to security settings.
The client attempted to work with a server entity to which it has no access because another client is working with it.
The client requested a method that was not allowed because some precondition failed.
The sender sent a malformed frame that the recipient could not decode. This strongly implies a programming error in the sending peer.
The sender sent a frame that contained illegal values for one or more fields. This strongly implies a programming error in the sending peer.
The client sent an invalid sequence of frames, attempting to perform an operation that was considered invalid by the server. This usually implies a programming error in the client.
The client attempted to work with a channel that had not been correctly opened. This most likely indicates a fault in the client layer.
The peer sent a frame that was not expected, usually in the context of a content header and body. This strongly indicates a fault in the peer's content processing.
The server could not complete the method because it lacked sufficient resources. This may be due to the client creating too many of some type of entity.
The client tried to work with some entity in a manner that is prohibited by the server, due to security settings or by some other criteria.
The client tried to use functionality that is not implemented in the server.
