Starting a couple of days ago, the 7206 started sending HUGE numbers (10x normal) of flows to my flow-collector. I’ve dug into the raw flow files and I just don’t see anything strange. All three routers carry about the same traffic load according to bandwidth, but the flows are out of the ball park for the 7206. It’s almost like the router is counting traffic multiple times, but the config didn’t change when this started.

If it's a single IP source or destination you can find it by aggregating on the IP address then sorting by flows.

# top 10 src IP sorted by flows
% flow-cat <data> | flow-report -vSORT=+flows -vTYPE=ip-source-address -vRPTOPT=-m10

# top 10 dest IP sorted by flows
% flow-cat <data> | flow-report -vSORT=+flows -vTYPE=ip-destination-address -vRPTOPT=-m10

The above examples will work with the 0.68 distribution. Prior to that you'll need a config file for flow-report. Something like:

stat-report default
  type ip-source-address
  output
    format ascii
    sort +flows

stat-definition default
  report default

or just use flow-stat which I'd like to kill off now since flow-report can do so much more.
