Hi Peter,
Yes, the ResponseEvent should be returned after the timeout with a null
response.
From the log, it is unclear why you do not get the event. Is there an
if-statement
that ignores the ResponseEvent with null response in your code?
Best regards,
Frank

Hi Frank,
If we are using asynchronous SNMP calls with SNMPv3, what should be
the behaviour in case of timeout, when you used wrong credentials such
as a wrong user name. Should the ResponseListener always be
triggered, with event.getResponse() = null, after the timeout?
I would expect that, but it looks like this is not what I'm seeing:
the ResponseListener does not seem to be triggered in that case. So
this means that our application never knows that a timeout occurred.
We are using currently SNMP4J 2.5.0. Debug logging from SNMP4J:
