The default value of the max_allowed_packet parameter in your MySQL server may not be large enough. Refer to this website for detailed information about the MySql configuration parameter.
 

...

Increasing the max_allowed_packet variable setting in your MySQL Server from the default (1M) to something like 16M (16777125) fixes the issue. To fix the issue temporarily, run the following commands:

  • mysql -u root
  • set global max_allowed_packet=16777216

To permanently set it, choose one of the two methods listed below:

  • You can add the parameter  - max_allowed_packet=16M to the mysqld command line or (mysqld_safe command line) as shown: 

 mysqld --max_allowed_packet=16M 

  • Edit the MySql configuration file (my.ini on Windows/ my.cnf on Mac OS) and add max_allowed_packet=16777216 to the [mysqld] section. 
Code Block
[mysqld]
max_allowed_packet = 16M
  • Restart MySQL.
  • Restart frevvo. 
  • The setting will permanently take effect.

On Mac OS, you can access the my.cnf file by typing

    • sudo vi /etc/my.cnf
 The location of the my.ini/my.cnf file varies by configuration.
