What
The result message field counting queued sends now explains itself: it counts only your own sends still waiting when the result was produced, queued sends may merge together, entries the system queued are not counted, and the field is missing on results from a fatal startup failure.
Evidence
User-initiated sends still waiting in the command queue when this result was produced.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
