Sorry the blackberry is truncating your original mail, but yes I have noticed the same thing on my setup. In my case I am using a custom rrdtool perl script. While not a fix for the actual problem, my workaround has been to use a CDEF in my rrdgraph command to set the value to 0 if it exceeds a sane maximum. I'm not sure off hand if mrtg has a similar capability but you might be able to set a max value for the graph so at least it won't skew the graph and hide the rest of the data points. Another option is to use a custom script to collect the values by grabbing the data from snmp and then sanitizing them prior to outputting to the value.
