Hi Garrett,
I'm not aware of a problem with softflowd. The records btw are around 7s apart
- so it looks unlikely, that it is the
same same flow.
If you do not have nsel records you may use the std formats to display the
records e.g. -o line
If you can not get arount this, I need to check with pfsense.
Cheers

Be nice to your netflow data. Use NfSen and nfdump :)
