[SNMP4J] SNMP Bulkwalk Parsing error.

[Frank Fock]

Hi,

First of all, OIDs do NOT start with a dot.

You can increase the inbound maxMessageSize with
http://www.snmp4j.org/doc/org/snmp4j/transport/DefaultUdpTransportMapping.html#setMaxInboundMessageSize(int)
but by default this is already set to the maximum 65535 bytes.

Thus, it seems that the agent has a bug and cannot handle its own buffer 
limits correctly.

Best regards,
Frank
