Why can MongoDB not see records after a certain date?

Question

MongoDB

Hello, I came across an interesting behavior of MoongoDB. After a certain date (10/14/2014), the database stopped seeing new records when sorted by date:

Any ideas what this could be are welcome.

Answer 1

I just noticed that you have an index by "create_date", and you sort by "create_time".
With a certain (large) number of documents without sorting, monga should not give a result at all for optimization purposes, it should give an error (depending on the version).
Previous answer: Try to dump/restore to another database, or db.repairDatabase, the database might be corrupted.

Answer 2

Well, port forwarding on the router must be configured.
