Change line 39 in the file $ZENHOME/Products/ZenRRD/zenperfsnmp.py to
be smaller than 40 (the current max value). 512 bytes for the
buffer, that's skimpy.

This is what Cisco has to say about that:
"
%PIX-3-212005: incoming SNMP request (number bytes) on interface
int_name
exceeds data buffer size, discarding this SNMP request.
Explanation This is an SNMP message. This message reports that
the length
of the incoming SNMP request, destined for the PIX Firewall,
exceeds the
size of the internal data buffer (512 bytes) used for storing the
request
during internal processing; therefore, PIX Firewall is unable to
process
this request. This does not affect the SNMP traffic passing through
the PIX
Firewall via any interface.
Action Have the SNMP management station resend the request with a
shorter
length, for example, instead of querying multiple MIB variables in one
request, try querying only one MIB variable in a request. This may
involve
modifying the configuration of the SNMP manager software.
"
Is there a way to force splitting the snmp request in smaller packets?
