How do I avoid the UnknownHostException in this line:
TransportMapping transport = new DefaultUdpTransportMapping();
I use the SNMP4J 2.2.0 API and use multiple threads (one thread for each switch)

Use a hostname that does exist? – user207421 Sep 25 '13 at 00:35

As this is obviously an SNMP4J issue, remove the general SNMP tag. – Lex Li Sep 25 '13 at 02:53

OK I got this fixed by calling
TransportMapping transport = new DefaultUdpTransportMapping();
only once for each thread. With 50 threads it still works fine.
My guess is that the networkIf / OS / Java was out of available ports
