How to Resolve "MYSQLi Error: User Already Has Maximum Active Connections"?

MYSQLi Error: User Already Has Maximum Active Connections

A recent error message, "MYSQLi error: User already has more than 'max_user_connections' active connections [duplicate]," has raised concerns about the database connectivity of a website. Upon investigation, it appears that the maximum allowable user connections have been exceeded, causing the error.

This is a configuration issue, not a programming problem. The database hosting provider or server administrator must adjust the 'max_user_connections' limit in the MySQL configuration file to allow more simultaneous connections.

Alternatively, a Singleton pattern can be implemented in the database connection class. This pattern ensures the reuse of a single connection pool, preventing further connection explosions.

In summary, the issue is related to limited server resources, and increasing the connection limit or adopting the Singleton pattern will resolve it.
