What happens?:
On July 13, I got this:
MediaWiki internal error.
Original exception: [c8466b8a-0c54-4456-8259-2e3fd3f4be95] 2024-07-13 19:12:17: Fatal exception of type "Wikimedia\Rdbms\DBUnexpectedError"
Exception caught inside exception handler.
Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.
I just got another one
MediaWiki internal error.
Original exception: [38973e56-81e9-4748-81c2-6735336e3a90] 2024-07-17 15:51:37: Fatal exception of type "Wikimedia\Rdbms\DBUnexpectedError"
Exception caught inside exception handler.
Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.
URL for today's was: https://en.wikipedia.org/w/index.php?title=Wikipedia:Arbitration/Requests/Case&curid=22747298&diff=1235079535&oldid=1235079140
I figure if I got two of them in a few days, it might be something significant, so logging this report.
