I get similar issues since a few versions back, server starts to max the CPU then stuff like this gets spammed in log.
After a some time, it calms down and everything is back to normal. Seems to happens alteast once every day.

Ive upgraded most hardware in server, thinkig it was ram issue. But problem remains with new hardware aswell.
