[tkined] Scotty bug??

Well, I am facing a wierd problem when using scotty to SNMP query a
router which is unreachable.
Ideally, I should always get a "noResponse" from this unreachable node.
But I see that I get a "noError"
response for an SNMP query made on such an unreachable node. I looked at
the varbind list associated
with this node whenever there is a "noError" returned and see that the
varbind list has some values instead of being NULL.

The error code returned from doing SNMP queries on such an unreachable
node flaps between "noResponse" and "noError" but on manually checking,
it is never reachable. Than how come scotty sees it as reachable?
Hence I wonder if scotty gets confused when it sees a node as
unreachable for long periods of time that it returns the results of
another node (which could be the reason that the varbind list is not
NULL).

Note: I am running my script doing SNMP queries on a lot of nodes
together using the Asynchronous (Callback) method.

Can anyone please let me know if you have encountered the problem
outlined above and also the solution if any ?

Thanks!
