Very very interesting but it does not look like as crash of XWayland process.

Comment 2 Olivier Fourdan 2017-09-22 07:48:35 UTC 
As indicated in downstream bug https://bugzilla.redhat.com/show_bug.cgi?id=1492469#c7, this is not a crash but libwayland itself exiting because Xwayland can't write to the socket:

  > Error sending request: Resource temporarily unavailable
  > [99334.060056] localhost.localdomain org.gnome.Shell.desktop[1821]: (EE)

That's from https://cgit.freedesktop.org/wayland/wayland/tree/src/wayland-client.c?h=1.14#n657

Can you please try with weston to see if the issue occurs with a different Wayland compositor?
