While evaluating CouchDB 1.3.0's automatic compaction daemon, I encountered an
error when the daemon tried to warn about insufficient free space:

It looks like this is being caused by the ?LOG_WARN macro referencing
couch_log:warn_on/1 (which does not exist and appears to be an artifact of
per-module log levels, a feature is not a part of 1.3.0) instead of
couch_log:warn_on/0.
