We are using a command to create the oplog (as part of resizing the oplog).

db.runCommand({ "create" : "oplog.rs", "capped" : true, "size" :

{ "$numberLong" : "2147483648" }

})

This returns error - specify size:<n> when capped is true, code - 14832. This used to work in previous version of the driver.

If you pass in the size directly as long it works
E.g. db.runCommand({ "create" : "oplog.rs", "capped" : true, "size" : 2147483648 });
