## Why Am I Getting \"Too Many Connections\" Errors on My GoDaddy MySQL Database Despite Only One User?

MySQL "Too Many Connections" Error

Problem

A user is experiencing "Too many connections..." errors while connecting to a MySQL database hosted by GoDaddy. The error occurs despite there being only one active user and functional code that establishes and closes database connections on each page.

Analysis

Shared-hosting providers often limit the number of concurrent connections allowed for a single user. The code appears to correctly handle connection management using mysql_connect with the default parameter of autoconnect set to false. However, the issue persists even with this setup, suggesting there may be an underlying issue.

Possible causes

• Server-side connections limit

  GoDaddy's Economy Package limits connections to 50 at a time, which could be exceeded if multiple browser tabs or parallel requests are active.

• Concurrent server usage

  Even with a sufficient connection limit, other users accessing the same MySQL server could exhaust the available connections, resulting in the "Too many connections" error for the individual user.

Solution

• Upgrade hosting package

  GoDaddy's Deluxe Package allows for 100 concurrent connections, which would provide a safer margin for 30 expected concurrent users.

• Contact GoDaddy support

  Confirm if the issue is due to server-side connection limits or other potential problems. They may have visibility into server-level metrics and provide further insight.

Additional notes

• Non-persistent connections are automatically closed by MySQL when the script ends without the need for explicit mysql_close() calls.
• Persistent connections should be avoided due to their potential for memory leaks and difficulties in resource management.
