That's disturbing. My system was fully up-to-date as of Friday, and I'm 
not seeing any pending updates for nfs-utils.
Perhaps it's a re-manifestation of the bug, or a new one which is 
similar in behavior.

I'm sorry then I don't know what happened to the logs because I don't 
have any others available.

If I see this issue again I'll be sure to save/post the log.
