Re: [paho-dev] Client be disconnected when keepAliveInterval more than 10 secs 
Charles,
thank you. On my system, the client throws an MqttException with the message "Connection lost (32109) - java.io.EOFException." 
If it is the same, I do not need to enter a duplicate.

best regards,

René.

As Dave says, getting an issue in the Bugzilla tracker will ensure
that we can look at it properly. Please add as much of the detail as
you can (including the timings etc you mentioned).

Regarding IA92, it's deprecated; doesn't support authentication; and
the license is not the same as Paho, so you may need to be careful
about using it in a commercial manner.

Thanks Dave, that was quick. I timed the timeout at a constant 2
minutes 38 seconds before adding the reconnect.
I'll have a look at the exception and will file an issue.

best regards,

René.

The Paho Java Client should keep the connection alive by sending
pings every keepalive interval if no other messages flow. If the
network is in good shape and the sever is running correctly it
should stay connected forever. Is Mosquitto putting out an error
stating it has killed the client as it has not received any
packets from the client? If that is the case it could be a bug
in the Java client. It is always 5 mins that the client is
disconnected?

Can you raise a bug on bugzilla against paho here with full
details? Paho bugzilla site can be found here:

Per Rene it is a good idea to code the connectionLost call back
to handle the case when a client disconnects abnormally e.g.
blip in the network....

Hi Charles,

I just reconnect when the connectionLost event comes in:

method connectionLost(t=Throwable)
do
connectAndSubscribe()
catch mqx=MqttException
log(mqx.getMessage())
end

(this is NetRexx source but you get the picture).

best regards,

René Jansen.
