Impossibly high network traffic reported

[Stephen Childs]

Hi,

We're noticing a problem with network traffic monitoring using Ganglia 
(and also Lemon) on our PowerEdge 1950s running Scientific Linux 4 
(~=RHEL4). Every now and then a node will report impossibly high network 
traffic (e.g. 10GB/s or more on a node with 1GBit cards). This throws out 
all the graphs for the cluster. Has anyone else seen this?

The kernel version is 2.6.9-55.ELlargesmp. Not exactly sure what the BIOS 
and firmware versions are.

Stephen
