I think this is the cause. For an explanation why a full fs causes a SIGBUS, see: <a href="http://cgit.freedesktop.org/wayland/wayland/commit/?id=011b6954031a25de8d9eb39631b6837553bb3cfb">http://cgit.freedesktop.org/wayland/wayland/commit/?id=011b6954031a25de8d9eb39631b6837553bb3cfb</a> Can you somehow check if the target memory is indeed mmapped from that fs and if so, how does the file get created? This would allow a graceful failure at least. I think the next question would be whether the mmap is of the expected size, and should something throttle/reclaim somewhere to avoid filling the fs.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
