Well, I only managed to replicate it on Ubuntu, and it requires many conditions to be met:
- 6in4 tunnel to HE.net
- ipv6 rules applied
- ipv6 forwarding enabled
Removing/replacing any one of these made downloading (wget -O /dev/null) reliable for at least 3 repeats of a large (~1GB+) downloads.
I recreated the setup on Raspbian, and so far haven't had the issue.
