mongodb Socket say send errno9 Bad file descriptor

This error message indicates that there is a problem with the MongoDB socket, specifically with the file descriptor assigned to it. A file descriptor is a unique identifier assigned by the operating system to a file or socket that allows programs to interact with it.

The error code "errno:9" indicates that the file descriptor is invalid or has been closed. This could be due to a number of reasons, such as a network issue, a problem with the MongoDB server, or an issue with the file descriptor itself.

To resolve this issue, you can try the following steps:

1. Restart the MongoDB server and check if the error persists.

2. Verify that the MongoDB server is running and accessible by other applications.

3. Check the network connections and make sure there are no issues with the network.

4. Check the file descriptor configuration and make sure it is set up correctly.

5. If the issue persists, you may need to seek further assistance from the MongoDB community or support team.
