XF 2.2 Running CRON Mass Email - DB Error

Screenshot attached.
Any ideas?

This would typically mean these MySQL config values aren't set high enough:

wait_timeout
max_allowed_packet

These can mean that longer running tasks can cause MySQL to disconnect before the code is finished.

How could this be increased? Guessing it's because it's trying to send the message to 1000's of users?

You set/change the values in the mysql.cnf file on the server.
