Error: Operation questions.find() Buffering Timed Out

This error occurs when your MongoDB query (specifically a find() operation on the questions collection) took longer than 10 seconds to execute and didn't return any data within that time limit.

Common Causes

1. Database connection issues: The connection to MongoDB might be slow or unstable

2. Large dataset: The questions collection might be very large without proper indexing

3. Complex query: Your find operation might be too complex or unoptimized

4. Server resource constraints: The database server might be under heavy load
