Please let me know which limit was exceeded, the database size? We use Action Scheduler instead of the default WordPress cron, it still uses the database for managing jobs but it may have an option for the server-level cron, this requires further research https://actionscheduler.org/
hello Ihor thank you for assistance. No, the database size is fine, but the default WordPress cron exceeded the php excutions in my hosting plan, I apply this solution and so far it seems good. if the problem backed again, I will try use Action Scheduler instead of the default WordPress cron.
