Error while publishing: "Destination is too short"

[sgeer21]

Hi, we are using RabbitMQ client 6.2.2. Getting following error intermittently while publishing the message:

Error while enqueuing Web App form submission. Error: System.ArgumentException:

Please suggest.

6.2.2 is over two years old and that entire code path has been replaced.

Line OutgoingCommand.cs:65 is

int maxBodyPayloadBytes = (int)(connection.FrameMax == 0 ? int.MaxValue : connection.FrameMax - EmptyFrameSize);

which does not access any actually mutable connection state (FrameMax is set once when a new connection is opened).

It's not clear to me what the "destination" is, perhaps it is the compiler that performs some copying under the hood and re-arranges the resulting code in a way that is not obvious.

Please upgrade to 6.6 or at least 6.4-6.5.
