[AGENT++] SNMPv3_MP_UNKNOWN_PDU_HANDLERS error

[Anurag Jain]

Jochen,
 
Appreciate your help ..and quick turn around , as usual !!! Good results so far.
 
We have been beating on the patch fix and have had no errors. 
We are running tests overnight on 2 systems but by now we would have seen many occurrences of the problem with the old code.
 
Regards,
Anurag
