Comment 1 Candido Campos 2020-01-28 10:29:14 UTC 
WA for cpu issue:

 restart the container.
Comment 2 Michele Baldessari 2020-01-28 16:00:25 UTC 
The log no logging bits will be addressed via https://bugzilla.redhat.com/show_bug.cgi?id=1739155 not sure if you want to close this as dupe of that or if you want to keep it open to track the 100% cpu usage
