So the result is this:
- version 1.6.6 or version 2.0.4 without "long lived graceful restart off" => fails
- version 1.6.6 or version 2.0.4 with "long lived graceful restart off" => succeeds

I generated a pcap for the failing sessions for both version 1.6.6 and version 2.0.4.

I will send the pcaps to you directly after submitting this email

Thanks!
