I ma having the same problem on a new target I added to an
existing config file: the first line of the log is updated, but
the rest of the lines are all zeros.
I looked at the values, changed them throughout the .log and .old
files, re-ran mrtg and they reverted to what they were before I
made the edits.

The OID was one I got from SOMIX's website and is supposed to show
memory utilization for a net-snmp host.
