Hi folks,

Recently we found the following kernel message of XFS. I don’t really know
how to read it in the right way to figure out the problem in the system.
Is there any known bug for
Linux-3.13.0-32-generic-x86_64-with-Ubuntu-14.04-trusty ? Or the problem is
on the swift-object-se rather than XFS itself ?

swift-object-se means swift-object-server which is a daemon handles data
from http to XFS. I can’t address the problem came from XFS or the daemon
swift-object-server.
Any idea would be appreciated.
