we have the same problem here, but what happened on my site is worse. an error occurs almost every 6 hours, and usually enough to restart MySQL but sometimes the server must restart too, maybe something is wrong on my website https://layarkaca21.world, need help as soon as possible. Running Ubuntu with 2gb ram VULTR, latest wordpress with ee v.3

How much space do you have on your drives?

Have you tried repairing through WPCLI?

Same is happening to my sites. The only option which helps - restart sites.
