I think this describes the same bug as described in https://bugs.centos.org/view.php?id=14073&nbn=3
Actually I am still experiencing this on Ubuntu 16.04.3 LTS (Kernel 4.4.0-101-generic). In particular I have seen that when I run a lot of Docker containers and they are killed because of OOM errors (because of using more memory than given to them by Docker), then frequently the machine freezes/dies and outputs the message below into the syslog: Feb 2 16:33:31 GPCL-GPU416 kernel: [2006550.602531] kernel BUG at /build/linux-SwhOyu/linux-4.4.0/fs/xfs/xfs_aops.c:1056!
