I have a database for which compaction is failing. When I run
compaction, I get errors in the CouchDB log like:

Lots of information here but I don't understand it and I haven't found a
description in the documentation.
What is the best way to learn about the structure and content of these
log messages? Is there some documentation somewhere?
