So it is not SSL.  Then it could be TCP Fast Open (server-side fast
open, from the logs I see this is the AXFR server).  Or perhaps the file
descriptor events could be mangled, in the event handling.  This patch
may help?  Otherwise, perhaps a stack trace of the issue could be useful
to have, or a way to reproduce it.


Best regards, Wouter
