Hello,

We're having problems with clients hanging with the following messages on the
client:

followed by the client hanging.  Nothing appears on the MDS or on the OSS in
question.  These symptoms were reported by another user, but there was no
resolution or workaround.  We're getting this about once per day on our head
nodes.  Has anyone had any luck with this issue?

Thanks,
Chris
