I got the same error using a standalone mongoDB 2.2, and found a way to fix
it.
I used the mongodump command as following:
mongodump --db twitter_nlp --collection home_timeline --out ->
home_timeline.bson
mongorestore gave me the following output:
$ mongorestore --db twitter_nlp --collection test home_timeline.bson
connected to: 127.0.0.1
Fri Sep 28 12:53:47 home_timeline.bson
Fri Sep 28 12:53:47 going into namespace [twitter_nlp.test]
Fri Sep 28 12:53:47 home_timeline.metadata.json not found. Skipping.
*assertion: 10264 invalid object size: 543781446*
If you remove the first line of the bson file, with the following command,
the mongorestore operation will work.
$ tail -n+2 home_timeline.bson > home_timeline_fix.bson
$ mongorestore --db twitter_nlp --collection test home_timeline_fix.bson
connected to: 127.0.0.1
Fri Sep 28 12:55:10 home_timeline_fix.bson
Fri Sep 28 12:55:10 going into namespace [twitter_nlp.test]
Fri Sep 28 12:55:10 home_timeline_fix.metadata.json not found. Skipping.
2516 objects found
NB: the first line of home_timeline.bson contains "Fri Sep 28 12:51:14
doing snapshot query",
which does not seem to be relevant for mongorestore.
