Additional info:
github comment on patch linked :

" I am the world's biggest moron.

of course there's a race condition, if you close the bloody socket before
setting the state to conn_closed. The amount of time I looked straight at it
and didn't see it is causing me physical pain."

customer reports being affected by this issue but has not provided any data to show he is. data will be collected and added to the bugzilla as is.
