Which linecards do you use to collect SNF? If this is an Engine3, you
can also do full Netflow (non-sampled) with v8 export at line-rate.

Two caches?

can you check the flow cache on the LC using

exec slot <n> sh ip cache flow
 and
exec slot <n> sh ip cache flow aggregation as

and see if you see flows in there..

"show ip flow export"  gives export info..

You are not exporting through the GRP/PRP management Fastethernet port,
do you? This is not supported..
