Hi Frank, Thanks a ton for such a quick reply. So you mean its game over? :(
Do you have any suggestions how I should handle this situation? The client does not want me to show SnmpTimeOut. Because when he checks from the Adventnet MibBrowser, he can see the value. Although it is an SNMP agent issue, I have been asked to handle it my application.

This IOException is caught and logged in DefaultUdpTransportMapping. So in my application I'll get ResponseEvent with a null PDU and i'll throw an SnmpTimeOutError as the response is null. > > The problem is that I do not want to show the error as an SnmpTimeOut. > I want to show the exact reason in my application.
