Answer:

This error message typically indicates that the connection pool for your database has reached its maximum size, and all connections are currently in use. As a result, the system is unable to obtain a new connection from the pool within the specified timeout period.

Here are a few possible solutions for this problem:

Increase the maximum size of the connection pool: If the connection pool is small, it may be filling up quickly, resulting in this error. You can increase the maximum size of the connection pool to allow more connections to be created and prevent the pool from becoming exhausted.

Improve connection management: Make sure that you are properly closing connections when you are done with them. Failing to do so can cause connections to remain open and consume resources, leading to this error.

Optimize database queries: If your application is making a large number of database queries that are slow to execute, this can cause connections to remain open for a long time and exhaust the connection pool. Try optimizing your database queries to improve their performance and reduce the time they take to execute.

Use connection pooling: If you are not already using connection pooling, consider implementing it. Connection pooling allows you to reuse existing connections rather than creating a new one each time a connection is needed, which can help reduce the number of connections being created and prevent the connection pool from becoming exhausted.

I hope this helps! Let me know if you have any further questions.
