  WordPress site intermittently experiences stale data rendering in highly concurrent AJAX-driven elements (e.g., live update feeds, dynamic user dashboards). Debugging reveals a race condition leading to premature invalidation of a specific object cache group (_transient_timeout_*) during simultaneous calls to wp_next_scheduled() on an AJAX endpoint that both queries and updates transient data. This results in WP_Object_Cache serving a false or expired value before the scheduled event can legitimately update the transient, causing data inconsistency until the next cache refresh cycle.
