I can't insert pictures into my database which are somewhat bigger than 400 kb. 

The problem exist with mysqlcc 0.9.3 (and also with a Java client connected with the J/Connector 3.0.7 up to 3.0.9). 

The server cancel the connection during storing the data and the client gives the message: ERROR 2006: MySQL server has gone away. 

The error doesent depends on the table type if have tested myIsam and InnoDD.

BTW. The max_allowed_packet is set to 128M on the client and the server.

How to repeat:
Try to store a jpg > 400 kb in a mediumblob or longblob with the mysqlcc image viewer.

Has server acknowledged the max_allowed_packet setting? What does
the following command output:

  show variables like 'max_allowed_packet';

Hi Indrik!

show variables like 'max_allowed_packet';

| Variable_name      | Value     |
| max_allowed_packet | 134216704 |

but, I found that the variable net_buffer_length 

| Variable_name     | Value   |
| net_buffer_length | 1048576 |

but in my.ini


However, the problem exist even with smaller files than << 1M.

Thanks Harald
