      Hi,
      I got the same issue with this one: SERVER-25285

      One different detail...

      I was able to start mongo using --repair however it would go down few seconds later when running some queries..

      The database crashed when I tried to dump using mongodump.
      Then I tried to dump the collections one by one.
      That dump worked for all the collections except by one called "user_photos"
      It is not a big collections, only 4554 documents.
      > db.user_photos.count()
      4554

      When running mongodump for this specific collection would make the mongo crash with same message on log:
