weave: Host unreachable: netlink error response: no such device

We are starting to see some strange weave behaviour on some of our weave clusters. Network connectivity seems to fail silently. When I try to ping a container I see

92 bytes from 10.21.102.67: Destination Host Unreachable

weave status peers, weave status connections, and weave status ipam did not show any warnings or errors

killing and starting a new weave router fixes the issue temporary, but it comes back after a random time (could be days, could be hours). Let me know of any additional info you would need to further debug this. Also if you can explain what this error means, or point to some documentation on how we got here and how to prevent this it would make me 😄

latest weave was running on the servers

# weave version
weave script 1.4.6
weave router 1.4.6
weave proxy  1.4.6

we only use weave router (not proxy or DNS or plugin) EDIT: detailed repo steps below
