MySQL has gone away

    Recently updated MySQL to 5.7.18 from 5.6.x. We noticed it got quiet so I ran the mail parser link manually and it shows the error below:

    Running parser for Queue ID '1': foo@nc-software.com Queue Total: 0, Accepted: 0, Rejected: 0 Running parser for Queue ID '2': foo2@nc-software.com Warning Router: https://helpdesk.nc-software.com/cron/Parser/ParserMinute/POP3IMAP PDO::exec(): MySQL server has gone away (D:/Webs/kayako/__swift/library/Database/class.SWIFT_Database.php:539)

    Using latest version of Kayako with PHP 5.6.30.

    Resolved - My.ini config issue and optimized all tables again.

    Can you please list the changes you made in my.ini?

    I don't recall all of the changes but essentially when I upgraded from MySQL 5.6 to 5.7 a new My.ini was used and I missed some of the migration from the former to the latter. The one that I think broke it was the max size either attachment or message, one of the size settings. To better view old vs. new I removed all of the commented (# prefix) lines so I could see just the config items and that helped identify the problem.
