Hi!
Currently I suppose that problem is in incorrect device response when using SNMP version 2c (or probably incorrect request from NetXMS, but I've never seen such behavior with any other devices). I'll add an option to disable automatic SNMP version detection during configuration poll so you will be able to force usage of SNMP version 1 and we will see if this helps.
Best regards,
Victor
