Hello.

While my java program is inserting data in mongodb, it started to show these errors below.

and mongo server was shut down.

And I tried to restart mongo server but it keeps being failed.

Below is final log.

It would be so nice if I can recover this server but if I can't, I would like to transfer these databases to new mongo server. 

There are some ways to dump database while the server is running but I can't use that way because my server is already dead. Hope I can find a way to use this server or restore the database.
