Well, this one means that it asked a client to revoke some file
capabilities 962 seconds ago, and the client still hasn't.

And this is a request from the same client to create a file, also
received ~962 seconds ago. This is probably blocked by the
aforementioned capability drop.

Everything that follows these have a good chance of being follow-on
effects. The issue will probably clear itself up if you just restart
the MDS.

We've fixed a lot of bugs around this recently (although it's an
ongoing source of them), so unless you're running very new code I
would just restart and not worry about it.
