Erreur de la base de données

Une erreur de syntaxe de la requête dans la base de données est survenue. Ceci peut indiquer un bogue dans le logiciel. La dernière requête traitée par la base de données était :

(SELECT `mw_recentchanges`.*,ts_tags FROM `mw_recentchanges` LEFT JOIN `mw_tag_summary` ON ((ts_rc_id=rc_id)) INNER JOIN `mw_pagelinks` ON ((rc_namespace = pl_namespace AND rc_title = pl_title)) WHERE (rc_timestamp >= '20240719000000') AND rc_bot = '0' AND (rc_user = 0) AND (rc_user_text != '18.117.183.99') AND pl_from = '1063' ORDER BY rc_timestamp DESC LIMIT 50 ) UNION (SELECT `mw_recentchanges`.*,ts_tags FROM `mw_recentchanges` LEFT JOIN `mw_tag_summary` ON ((ts_rc_id=rc_id)) INNER JOIN `mw_templatelinks` ON ((rc_namespace = tl_namespace AND rc_title = tl_title)) WHERE (rc_timestamp >= '20240719000000') AND rc_bot = '0' AND (rc_user = 0) AND (rc_user_text != '18.117.183.99') AND tl_from = '1063' ORDER BY rc_timestamp DESC LIMIT 50 ) UNION (SELECT `mw_recentchanges`.*,ts_tags FROM `mw_recentchanges` LEFT JOIN `mw_tag_summary` ON ((ts_rc_id=rc_id)) INNER JOIN `mw_imagelinks` ON ((rc_title = il_to)) WHERE (rc_timestamp >= '20240719000000') AND rc_bot = '0' AND (rc_user = 0) AND (rc_user_text != '18.117.183.99') AND il_from = '1063' AND rc_namespace = '6' ORDER BY rc_timestamp DESC LIMIT 50 ) ORDER BY rc_timestamp DESC LIMIT 50

depuis la fonction « SpecialRecentchangeslinked::doMainQuery ». La base de données a renvoyé l’erreur « 1213 : Deadlock found when trying to get lock; try restarting transaction (formationnmercur.mysql.db) ».
