OTRS backup.pl - Error 2020: Got packet bigger than 'max_allowed_packet bytes

Dump MySQL rdbms … mysqldump: Error 2020: Got packet bigger than ‘max_allowed_packet’ bytes when dumping table ‘article_plain’ at row: 8704 … failed

Before running backup.pl to back up your OTRS installation, it might be preferable to add the the max_allowed_packet directive to the MySQL configuration file.

Modify /etc/my.cnf to include the following section:

[mysqldump]
max_allowed_packet = 50M

Restart the MySQL server to have the changes take effect.
