MySQL server has gone away - in exactly 60 seconds

The "MySQL server has gone away" error message typically indicates that the connection to the MySQL server was lost.

This error message can occur for a number of reasons, such as:

1. The MySQL server process has terminated unexpectedly.
2. The connection to the MySQL server was lost due to a network issue.
3. The MySQL server connection timeout period (default is 8 hours) has been exceeded.
4. The max_allowed_packet variable in the MySQL server configuration is set to a value that is too low.

Regarding the details you've provided, "gone away in exactly 60 seconds": MySQL's default wait_timeout is 28,800 seconds (8 hours), so an exact 60-second timeout usually originates from an application connection pool, web server, or load balancer rather than the database itself. To verify the server's actual timeout settings, run:

SHOW VARIABLES LIKE 'wait_timeout';

If the timeout is indeed too low, you can adjust it temporarily with:

SET GLOBAL wait_timeout = 28800;

For persistent changes, update wait_timeout in your my.cnf or my.ini configuration file and restart the MySQL service.
