Publishing a draft of table field causes internal server error

[karltriest]

Description

making a draft of a table field then publishing that draft causes "An internal server error occurred."

Steps to reproduce

1. enter data to a table row
2. publish draft
3. publish changes

*note: publishing the exact same data without first making a draft works fine

@karltriest The MySQL docs have a whole page dedicated to that "MySQL server has gone away" message (https://dev.mysql.com/doc/refman/8.0/en/gone-away.html), but 9 times out of 10 when we see it, it's because you need to bump your MySQL server's max_allowed_packet and/or wait_timeout settings to higher values.

[karltriest]

@angrybrad I changed the MySQL options to max_allowed_packet to 67108864 (64MB), (default/was 4MB) supposedly the default for wait_timeout on mysql is 28800 (8 hours), so i don't think that was an issue but I added in 28800 just in case.

Unfortunately the bug persists.

[angrybrad]

@karltriest did you verify the settings took? i.e. SHOW VARIABLES LIKE '%max_allowed_packet%';

If they did, the other setting I've setting that works is bumping innodb_log_file_size higher.

[karltriest]

@angrybrad turns out that it was the max_allowed_packet setting, and the server needed a reboot in order for the setting to take.
thanks! really appreciate your help

[angrybrad]

@karltriest glad you're all sorted!
