Answer 1

You need change your max_allowed_packet to a higher value in your my.ini configuration file.

Packet Too Large

A communication packet is a single SQL statement sent to the MySQL server, a single row that is sent to the client, or a binary log event sent from a master replication server to a slave.

The largest possible packet that can be transmitted to or from a MySQL 5.5 server or client is 1GB.
