Actually, I'm not sure if I can assert that these are all manifestations
of the same bug- was a netns-delete involved in this one as well?
I see:

This appears to be for a looped back packet, and looks like there
are problems with some rds_sock that got removed from the bind_hash_table..
According to the report, socket was created at

This is all uspace created rds sockets, and while there may be an
unrelated bug here, I'm not sure I see the netns/kernel-socket
connection.. can you please clarify if this was also seen in some netns
context?
