Thanks for the review! If I recall correctly, Felix reported that your original patch didn't help, though, so probably this one doesn't either. We should track that down before we go farther, I guess.

The ManageEngine netflow collector claims to work with ipfix but SFAICT it does not so I'm not going to waste more time on it.

In case you know a little Go, here is my script to test my IPFIX setup. I also use Wireshark which works quite well. I'll look into it too, today.

All the ipfix collectors that I can afford (i.e. free) take a lot of work to get configured and working correctly. I'd prefer to spend time working on the actual problem here and I can get an ipfix collector set up later.

Once I can start > collecting and analyzing the work should proceed quickly. I never applied this patch (from June) because we were continuing to look deeper. I don't know whether that ever bore fruit. Should I apply this patch now? Thanks, Ben.
