NodeBB Fails to Start - Logs Tell Nothing

The process just dies almost instantly. Nothing more happens. Other instances are running on the same database no problem.

Fixed and very important to know.... if you upgrade from MongoDB 2.4 to 2.6, all of your NodeBB instances will keep working happily until the apps themselves restart. At which time they will fail to authenticate. The issue is, you need to recreate the user(s) under 2.6:

Ooof, yes, I noticed that as well. I had to re-run the db.createUser command again. Good catch!

For the database, sorry.
