Be sure to not send a set of queries that are larger than max_allowed_packet size on your MySQL server. If you do, you'll get an error like:
Mysql Error (1153): Got a packet bigger than 'max_allowed_packet' bytes
To see your MySQL size limitation, run the following query: show variables like 'max_allowed_packet';
