"MySQL-Server has gone away"#

Problem#

mysql-server-has-gone-away.png

When accessing i-doit, the error message "MySQL-Server has gone away" appears. The cause is usually a value for max_allowed_packet that is too low.

Solution#

Increase the value of max_allowed_packet in the MySQL/MariaDB configuration file:

1
max_allowed_packet = 128M

Then restart the MySQL/MariaDB service. Further recommended values can be found in our system settings.
