Release procedures, code reviews, and testing are identified as contributing factors in bug.
With the contributing factors of release procedures, code reviews, and testing, the Apache CouchDB developers have put out a warning of a bug in the Apache CouchDB 1.0.0 that could lead to data loss. The bug is specific to CouchDB 1.0.0 where users have set the delayed_commits value to true. Developers are saying that once the bug is hit in code any subsequent writes to the database are not being committed to disk. A hot fix is available and a new release will be out this week.
