Transient failure, followed by a successful run, resolving.

@RLazarus For the task's records (and so we can keep track of what causes these failures, I guess), is there still an available stack trace/error message for what caused this and/or T424985: MediaWiki periodic job update-special-pages-s6 failed?

Relevant log lines from this one:

enwiktionary Mostlinkedtemplates            [QueryPage] Wikimedia\Rdbms\DBQueryDisconnectedError from line 1228 of /srv/mediawiki/php-1.46.0-wmf.26/includes/libs/Rdbms/Database/Database.php: A connection error occurred during a query. 
enwiktionary Error: 2006 MySQL server has gone away

That's "Culprit #2" in T422486.

From T424985 there are no errors in the logs.

RLazarus added a parent task: T422486: MediaWiki periodic job failures due to timeouts.May 11 2026, 7:32 PM
