The current agent code "downgrades" a getbulk request to a getnext
request. This is actually to some extend legal, but definately not the
purpose of having getbulk in the first place. Fixing the code to do a
better job however requires some serious work since you need to take
care of the message size restrictions and SNMPv2c has no way to
communicate the max. message size between the generator and responder.
So what the only safe thing to do is to assume 484 bytes, which will
give you only a very limited speedup.

This is definitely a bug - you should not get a tooBig error. I
checked the 3.0.0 snapshot code and it does not show this behaviour
anymore.

Correct.

Someone must fix the agent code.
