Depending on what goals you were trying to achieve with the
multiple-interfaces, one option might be to swap the "random()" for
something based on a consistent hash of message properties.
That way you could still get load balanced over the interfaces but a given
message would always select the same interface and you wouldn't have to
store any extra state.
Best wishes,
