does the command:
snmpwalk localhost public enterprises.ucdavis.memory
on the command line give any output?
If not, snmpd may not be running, your community may be wrong or you
packet filter may be blocking you from connecting to udp port 161, to
name a few things.
b.t.w., your stepsize is 60 seconds, and you're updating your rrd every
10 seconds..
