From the below log, it shows the RangeDeleter is blocked by the same cursor ids for 10+ hours. However from currentOp I can't find any long run operation. Is there any way to kill this cursors?

ramon.fernandez It's expected that the notimeout cursor still open even all the mongos are restarted? |

bydsky, you may want to consider using a default cursor timeout ( Since this is expected behavior I'm going to close this ticket. For MongoDB-related support discussion please post on the mongodb-user group or Stack Overflow with the mongodb tag, where your question will reach a larger audience. A question like this involving more discussion would be best posted on the mongodb-user group. See also our Technical Support page for additional support resources. Regards, |

We guess it may be related to https://github.com/MongoEngine/mongoengine/pull/1304. MongoEngine uses noCursorTimeout by default. |
