Ivan Kelly commented on BOOKKEEPER-695:
---------------------------------------
I've seen this before. Basically, you'll get one of these entry logs if you
shutdown while an entry is being written. This is a pretty normal case. I think
we should just log a warning.
> Some entry logs are not removed from the bookie storage
