If anyone out there has ever seen this before, I would really like to know
what is going on. This has been going on for a couple weeks. It happens
randomly between our 4 PM3's. The attached link is to our MRTG graph
showing a HUGE spike in Ethernet ectivity coming from our PM3. This is
actually one of the worst ones. It happens at any time of the day and
ranges anywhere from a spike of 90k up to 250k of input and output for only
a few minutes. This is happening locally on our ethernet becuase our T1
MRTG graph does not show any spikes in transmission, but our Ethernet MRTG
graph does show these spike in the same spots. A couple times it has
happened on multiple PM3's in one day but mostly just once a day or so. We
are in the process of trying to figure out what other machines on the
network are also showing a spike but we have some machines that we cannot
monitor with MRTG. Here is the link:

Any ideas?
