1. zmfixperms doesn't change the owner of these folders. I tried it.
2. What seems to have worked for me is the suggestion from another forum post to a) change the owner of the root-owned zmstat folders to zimbra:zimbra, b) then as root run "/opt/zimbra/bin/zmsyslogsetup", c) run zmcontrol stop, zmcontrol start.
Since I have done those steps (a couple weeks since the first occurrence), none of the servers that have hit this bug have had a recurrence.
For me and for now 'zmfixperms -extended -verbose' seems to have fixed the problem. Stopped zimbra, ran 'zmfixperms -extended -verbose', started zimbra and stats has been working again. Remark: another user pointed out that the problem has appeared again as he rebooted the server. Unfortunately, I neither can confirm nor decline this because I can not reboot the server right now. It's a production system...

chown -R zimbra /opt/zimbra/zmstat/
su - zimbra
seems to have fixed the problem here
