I'm not sure about the root cause of your crash, but I just wanted to
mention that before you blow away this filesystem, you should probably
try repairing it with a recent version of xfs_repair (like 3.0.0).
It also happens to the same filesystem each time (maybe because
it does the heavy I/O),a and it is also the same filesystem where
xfs_repair hangs in an endless loop often (but not always). (see
The filesystem was created a month or so ago using blocksize of 512 and
lazy-count=1, but I have many of those xfs filesystems.
Since this is a production system and I have no backup abilities, I have
to no choice but to reformat the disk now.
Also, I have seen similar problems to those described in Debian bug
525880 with xfs_repair not making progress (although I'm running
32-bit), and adding "-P" to the xfs_repair invocation helped in many cases.
