CU with 4.6.18 on VMWare got alert from AlertManager that chrony is not sync, random nodes at random time. They didn't change or update anything.

possibly related to 
https://bugzilla.redhat.com/show_bug.cgi?id=1874340
https://bugzilla.redhat.com/show_bug.cgi?id=1949493

but still could be an issue with Dynatrace operator (similar to case #02843340) they run.

As suggested by Timothée Ravier (on Slack channel wg-dynatrace), customer did run 'semodule -DB' to rebuild policies, but that didn't change anything and NTP issues still persist. Audit log shows AVC denials for chrony and timedatex.

All big logs like must-gather are attached in case #02968314
Comment 5 Timothée Ravier 2021-06-25 12:57:40 UTC 
Can you confirm that they rebooted the nodes after running `semodule -B` (or `-DB`)?
Comment 6 Micah Abbott 2021-07-12 19:39:58 UTC 
Is there any more information about this problem?

It appears we are waiting for confirmation that the `semodule -B` workaround was tried.
