I'm having this issue as well, but on Raspbian 10. Symptoms seems the same, generally occurs with high load. However, I don't seem to need IPv6 packets to cause this - my network is IPv4 only.
I thought I had a power problem because I am also using an external HDD (it's also working as a NAS), but with the powered hub things aren't any better.
