same here. I'm seeing one entry added to /var/log/messages every 4 seconds and 10% cpu load servicing the fallout from this selinux denial.

SELinux is preventing /usr/libexec/accounts-daemon from read access on the directory /var/log.
***** Plugin catchall (100. confidence) suggests ***************************
If you believe that accounts-daemon should be allowed read access on the log directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep accounts-daemon /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Since I was watching /var/log/messages prior to my lastest yum update and didn't see these messages, I'm pretty sure it's fairly new. The below message in /var/log/messages is repeated about once every 5 seconds "forever", so it's kind of annoying.
