This message is flooding my syslog on each snmp query.

To avoid it you have to change the log level of the services. In debian squeeze edit /etc/default/snmpd and change these lines:
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I -smux -p /var/run/snmpd.pid' TRAPDOPTS='-Lsd -p /var/run/snmptrapd.pid'
to:
SNMPDOPTS='-LS6d -Lf /dev/null -u snmp -g snmp -I -smux -p /var/run/snmpd.pid' TRAPDOPTS='-LS6d -p /var/run/snmptrapd.pid'
