[paho-dev] Maximum number of inflight messages exceeded

[Tito Cheriachan <titomc@xxxxxxxxx>]

Hi all,

I am using the paho mqtt java client and I was sending out a lot of messages every second , but the mqtt connection was not established , then I encountered an exception like maximum number of in flight messages exceeded.

1. Does this happen if the mqtt is not able to push out messages to the broker ?

2.will it happen on all qos levels ?

3.On what all scenarios will this occur.
