What to do with the following error: "InnoDB: ERROR: the age of the last checkpoint is xxxxxxx"

You just need to update your MySQL/MariaDB my.ini configuration file with innodb_log_file_size value at least ten times bigger than max_allowed_packet.
So for instance if you have max_allowed_packet=100M in the [mysqld] section, just ensure you haveinnodb_log_file_size=1G as well.
