Hi Christy,

Attachments cannot be sent through the mailing list.
I assume that the agent does not implement lexicographic ordering correctly. Some situations can be detected by TableUtils, but not all.

Maybe you can send me the logs directly to support at agentpp.com?

Best regards,
Frank

Hi Vinod,

You do not have to change anything on OS level.
With SNMP you cannot send packets that exceed 64K.
But I do not think that this is the problem here.
I guess that you modify the PDU contents while it is being encoded. Have you checked that already?

Best regards,
Frank
