[mosquitto-dev] Maybe found a bug: Received publish not being ack'd with QOS=2 and `max_inflight_messages 1`
|
I have the mosquitto broker running with `max_inflight_messages 1` in
a very slow 6lowpan network.
What the log below is showing is that the broker ignored a PUBLISH
(the m3) from the client.
Is this the expected behaviour? Should `max_inflight_messages 1`
ignore reception as well?
```
