_mongorestore_ fails to restore a dump containing a collection called "fs.chunks" (used by [GridFS][1]).

It looks like the chunks in this collection are too big (~32MB).

$ mongorestore <exportDataDestination>
...
Failed: my_db.fs.chunks: error restoring from my_dump/my_db/fs.chunks.bson: insertion error: EOF

Notes:

• Mongo version: 3.1.9
• Dump was generated using mongodump tool (no error/warning during creation, mongo version was 3.0.7)
• Restoration seems to work fine on all other collections
