Document MongoDB error codes

Using the github.com/go-mgo/mgo driver and the latest stable version of MongoDB, I observe the following error:

&QueryError

{ Code: 17406, Message: "getMore executor error: CappedPositionLost: CollectionScan died due to failure to restore tailable cursor position. Last seen record id: RecordId(200138)", Assertion: false, }

I cannot find information about error code 17406 anywhere. More broadly, I cannot find information about MongoDB error codes. This page contains a list of codes: https://github.com/mongodb/mongo/blob/master/src/mongo/base/error_codes.err. However, the highest error code in the file is 13000.

This page contains exit codes: https://docs.mongodb.com/manual/reference/exit-codes/ However, the highest code provided is code 100.

Searching Google for 'mongodb error codes' yields the following Google Groups thread: https://groups.google.com/forum/#!topic/mongodb-user/cKV3rJVRfqEhttps://groups.google.com/forum/#!topic/mongodb-user/cKV3rJVRfqE. One of the links (https://github.com/mongodb/mongo/blob/master/docs/errors.md) returns a page not found.

A list of PostgreSQL error codes is the top result when searching for "Postgres error codes" and can be found here: https://www.postgresql.org/docs/9.6/static/errcodes-appendix.html

A list of MySQL error codes is the top result when searching for "MySQL error codes" and can be found here: https://dev.mysql.com/doc/refman/5.5/en/error-messages-server.html

I am curious if a similar list exists for MongoDB. I attempted to ask a question about this on StackOverflow, however it will probably be closed by the time you read this.
