Question

Today one of my websites started showing

Error Number: 2006
MySQL server has gone away

It\'s a low-traffic client site running under Apache 2.2.9 (Debian

Answer 1

Since the other sites work, we can assume that it is related to your site (and not the server). The official documents mention that this might happen if you try to execute queries after the server connection is closed. Do you have any hooks in CodeIgniter that does something towards the end of a request where the database connection might be closed?
