This is a server issue. See this: http://www.vbulletin.com/docs/html/troubleshoot_mysql_goneaway and this: http://www.vbulletin.com/forum/showthread.php?s=&postid=310265#post310265

If it's only every once in awhile, I wouldn't worry about it. If it's many times a day, then I'd read those threads and see about making some changes to your config files.
