PDOE Exception?

Hi. I am about ready to start configuring the Mailpoet3 plugin but I am getting the following dashboard error messages that I have not experienced before with any other plugins. I am also now noticing that backend edits making database r/w are causing the page to just spin (not finish task). Wondering if I am the only one experiencing this?

MailPoet Error: PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away in /home/my/public_html/wp-content/plugins/mailpoet/vendor/j4mie/idiorm/idiorm.php:503
