Guys, I've seen similar issue reported in TOOLS-421 and TOOLS-435

mongorestore fails with `Failed: restore error: medstream.articles: error restoring from dump/medstream/articles.bson: insertion error: EOF`

In mongod log I see following message

`2015-10-28T21:58:13.646+0000 I - [conn15] Assertion: 10334:BSONObj size: 33438546 (0x1FE3B52) is invalid. Size must be between 0 and 16793600(16MB) First element: insert: "articles"

It blocks me completely form using database. I'd love to try changing `batchSize` but I cannot find where I can set while using mongorestore.

Could you please help me ?
