The cause for MySQL has gone away errors is that your server is not configured correctly, or not powerful enough, to handle your current traffic.
This manual entry will tell you more information about the error:
http://dev.mysql.com/doc/refman/5.7/en/gone-away.html
Most commonly it's the timeout settings referred to on that page that's the cause, so if this is an ongoing problem I would recommend looking into those first and foremost.
