Magento 2.2: The heartbeat cron jobs that run every minute spike CPU to 100% for a second. Is this normal? I have other services running on my server (2 core 4MB Linode) and the Magento cron job is causing problems.
I installed Wyomind OE Scheduler so I can see what runs and there are no obvious errors or abnormalities. I am not sure how to troubleshot beyond that.
I upgraded from 2.2.2 to 2.2.3 and saw no change.
