Re: [paho-dev] Maximum number of inflight messages exceeded
|
Hi Tito,
in the Java client, there is an internal setting of 10 QoS 1 or 2
messages that can be "in-flight" (unfinished protocol exchanges) at one
time. It is a temporary condition that will be resolved once the
sending of at least one message has been completed.
So the application should try again in a short period of time. If you
are using the async API, you could wait until a callback is made telling
you that the next message has been sent.
It does not apply to QoS 0 messages as there are no ACKs nor message ids
in that case.

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.
