[SNMP4J] TcpAddress issue

[Frank Fock]

Hi Joe,

There is no obvious error in what you wrote. So could you please provide us
the SNMP4J related part of the stack trace? This might help to find the 
root cause.

What happened in the past was often when people tried to test a simple 
setup,
that the main thread finished and closed the Snmp class (stopping all 
transport
listeners) before the request was send out. But since you seem to be using
a synchronous call, this seems to be unlikely here.

Best regards,
Frank
