Just to add a little note, pay special attention to the lines which say

-->Both the client and the server have their own max_allowed_packet
variable, so if you want to handle big packets, you must increase this
variable both in the client and in the server.

-->If you are using the mysql client program, its default
max_allowed_packet variable is 16MB. --To set a larger value, start
mysql like this:

-->shell> mysql --max_allowed_packet=3D32M

-->That sets the packet size to 32MB.

So thats the catch here...
