问题 I have a script which runs when my debian 6.0 server is deployed and it is designed to build postgreSQL from source, create a system user for it, create a database and start it running.

问题 The Problem My MySQL database works fine for my web application. However, when I try to open the database with phpMyAdmin, I get this error message: #2006 - MySQL server has gone away And phpMyAdmin disconnects back to the login screen. Other databases work fine.
