[Bug 1533043] Re: AUFS can hang up; Please update to v20160111


For what it's worth, Dockerized containers running common open-source
applications (Cassandra, Mongo, Flynn) have stumbled hard on this - and
of course, it's not just on Ubuntu, but all Linux kernels with
296291cdd: https://bugzilla.kernel.org/show_bug.cgi?id=109971 -

Akihiro has been a champion in tracking down the cause, reproduction of
the problem, a patch, and pushing for a fix in all the right places.
Give this guy a high five or a beer if you know him in person, he's
helping a lot of people out with his efforts.

  AUFS can hang up; Please update to v20160111

Status in linux package in Ubuntu:

Bug description:

  Many docker users have been experiencing this issue:

  The issue has been fixed since AUFS v20160111: http://permalink.gmane.org/gmane.linux.file-systems.aufs.user/5345
  So I suggest updating AUFS to v20160111.
