Hi,
as many other on jira.mongodb.org I faced with the same situation. Mongodb/server has unexpected shutdown. After startup mongo print out error listed below. I've tried --repair and other suggestions that google finds, but didn't helped.
If some could help me I would be extremely grateful.
Thank you.
