Large Number of SnmpSessions hanging

Agent Toolkit Java Edition

Hi,

In our application we are creating a SnmpAgent, and register a TrapListener

This is the code snippet from the class which extends SnmpAgent.

-------------------------------------------------------------------------

Â SnmpTrapService trapListener = null;

trapListener = new SnmpTrapService(trapSendingPort);

super.setAsyncMode(true);

super.setMaxThreads(2);

forwardingTable = new com.adventnet.snmp.snmp2.agent.ForwardingTable(trapListener,"V1V2TrapForwardingTable.xml","xml");

trapListener.setTrapForwardingTable(forwardingTable);

forTable = new com.adventnet.snmp.snmp2.agent.SimpleTrapForwardingTable(forwardingTable);

trapListener.setHandler(forTable);

forTable.addRegistrationListener(hdlr);

super.addSnmpPduRequestListener(hdlr);

super.addTrapRequestListener((TrapRequestListener)trapListener);

super.setDefaultTrap(false);

######################################################

Here is how the traps are being sent

-----------------------------------------------------

TrapRequestEvent te = Â new TrapRequestEvent(this,

varbindVector,

TrapRequestEvent.TFTABLE,

".1.3.6.1.4.1.94.7.1.3.0",

5);

te.setTimeTicks(agentRef.getUpTime());

trapListener.sendTrap(te);

The Problem is that after some times the SNMP master agent stops receiving the traps. And the number of SnmpSession objects starts increasing. This causes the JAVA heap to increase and eventually crash.

Can anyone help se to why the number of SnmpSession starts increasing?

Note : In SnmpStartup.xml file for the parameter Protocol please pass the value as TCP instead of TCP/IP, it works fine. And refer the AgentStartup.dtd for details on possible enumerated values for various config parameters.

Hi,

Greetings.

We would like to inform you that AgentStartup.dtd file is not generated for a particular agent, it's to validate the values of config parameters.

If your requirement is to change the configurations of the agent then you need to change only the configuration files of that particular agent and should not modify the dtd file of that agent.

Our suggestion for your requirement is to use our latest version product. As these issues has been fixed in our latest version of the product(WebNMS Agent Toolkit Java Edition 6.0.3).

Thanks & Regards,
