Hi folks,

Recently we found the following= kernel message of XFS. I don=E2=80=99t really know how to read it in the r= ight 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-trus= ty ? Or the problem is on the swift-object-se rather than XFS itself ?

swift-object-s= e means swift-object-server which is a daemon handles data from http= to XFS. I can=E2=80=99t address the problem came from XFS or the daemon sw= ift-object-server.
Any idea would be appreciated.
