[mrtg] Troubleshooting MRTG Error message

[Mersberger, Robert]

I need Help.  I am monitoring several HP GbE2 interconnect switches but
I only have problems shown below with one particular switch and the
problem only happens about 5 times in a 24 hour period.
Can any one assist me in finding out what is causing this.  Could it be
period of too heavy traffic on the network or might this be more of an
equipment problem?

Here is the message I get. 
Interfaces start at index 256 and index 258 is the 1st one on the switch
that has ifOperStatus.258 : INTEGER: up
