RHEL8 - ksmtuned using 100% cpu

Latest response

Bare metal Test system based on RHEL 8.1
After running for months with "zero cpu"
ksmtuned is suddenly using 100% cpu, 2020-07-10

Note that there are two processes running, and only one of them is using high CPU.
After restart of ksmtuned, the CPU has returned to normal
There were some reports about this back in RHEL 6, but I can't find anything for Jul 2020.
There's a config file '/etc/ksmtuned.conf' where you can enable logging, but this (by default) is all commented out.
I have not tested RHEL 8.2 yet
