    Description

      mongodump exits with a successful (0) exit status after emitting this message:

      Failed: archive writer: error reading collection: Executor error during find command: CappedPositionLost: CollectionScan died due to position in capped collection being deleted. Last seen record id: RecordId(170604747) / Mux ending but selectCases still open 4

      The database is not fully dumped when mongodump exits.

      The only capped collection is system.profile. The database server is a standalone mongod instance, not in a replica set. The mongodump command line is:

      mongodump -u <user> -p <password> --authenticationDatabase <auth db> --verbose --archive --gzip

      Will this happen with other capped collections, too?
