The UsmUserTable class uses the not thread safe TreeMap. It seems that if one thread were to do snmp.getUSM().addUser() while another thread were doing getUser() the iterator would throw a ConcurrentModificationException.
We see that if we run two or more threads to do SNMPv3 queries, sometimes one or more of the queries will simply time out and not return any data but sometimes succeed. _______________________________________________ SNMP4J mailing list SNMP4J@agentpp.org http://lists.agentpp.org/mailman/listinfo/snmp4j
