[AGENT++] Max PDU VB size...

I assume that you did recompile snmp++ after changing the file...

... so this error is either from the agent: The PDU with all Oids and 
values cannot be encoded/sent because of a limit in the agent.

Or the response is too big for snmp++: In this case you have to change 
the following define in config_snmp_pp.h:

//! The maximum size of a message that can be sent or received.
#define MAX_SNMP_PACKET 4096

The recommended solution is to split up the request into multiple 
smaller requests, but raising the max pdu size should work, too.
