Error: "User XXX already has more than max_user_connections active connections"

If you see the following message while browsing your site or in system logs:

"User XXX already has more than max_user_connections active connections"

it means that the script is opening too many connections to the database, or the site has a high number of simultaneous users.

Common Causes

• Unoptimized scripts that open new connections without closing them.
• Missing mysql_close() at the end of script execution.
• Genuinely high traffic on the site with many concurrent accesses.

Possible Solutions

• Use mysql_reconnect before each query to reuse existing connections.
• Ensure all scripts include mysql_close() to properly close connections.
• If the scripts are already optimized but traffic is truly high, contact technical support to:
  • evaluate increasing the max_user_connections limit;
  • or consider upgrading your hosting plan.

Note

An excessive number of simultaneous connections can slow down or crash the site. It's essential to both optimize your code and ensure the server has adequate resources.
