can not force scan on node with an error in event

Description

Hi,

i really stuck on error that i got when i want to force scan on node in opennms. there is an error like this :

The Node with Id: 129; ForeignSource: ; ForeignId: has aborted for the following reason: Aborting node scan : Agent failed while scanning the IP address tables : Unexpected error occurred processing IP address tables for /10.10.191.33: java.lang.NullPointerException

so when i want to add a new service , i must delete the node and re adding node to get the service monitored.

does anyone know how to fix this issue ?

Thanks Tarus for your clue,

so, the device that you mean is my opennms or the device that monitored in opennms ? and what device that i must disable discovery of the snmp service ?

however, when i ran snmpwalk on my opennms server, there is no problem with the query to the device.

This is an issue with the SNMP agent on your device and not a bug. OpenNMS is trying to access the IP address list in the ipAddrTable and is unable to do so. You either need to disable discovery of the SNMP service or fix permission on your device so that an snmpwalk correctly returns the ifTable and the ipAddrTable.

Won't Fix
