You wanted me to upgrade, here it is @Chris D :).
 
"MySQL server has gone away" indicates that the MySQL server has shutdown or otherwise closed the connection.

There are some settings that can be changed which may help. There's a similar thread here (albeit for XF 1.5):

Ultimately, though, it's a server issue.
