We just do not know what to do with that error.
Pretty much it means nothing can be done about it.
There is no recovery path, no collection and resend, since it may lead to dos.

Its like knowing that udp packet get lost, but you do not have enough
buffer space to save it and block. Actually there is no buffer at all.
Kind of missed interrupt.
