The agent sends a message which scotty can't read since the buffer
provided by scotty is too small (16K in 3.0.0, 2K in 2.1.X). You can
change this constant (TNM_SNMP_MAXSIZE) in tnm/snmp/tnmSnmp.h.
Note that SNMPv2c does not allow to "negotiate" the max. message size
between SNMP engines hence an agent which returns big responses is
likely to cause interoperability problems like this. SNMPv3 fixes this
