Perl didn't run "forever," and logwatch ran fine - just to rule these out. Thanks. Also occurs with updated kernel and SELinux policy:
SELinux is preventing /usr/sbin/mdadm from read access on the chr_file fb0.
***** Plugin catchall (100. confidence) suggests ***************************
If you believe that mdadm should be allowed read access on the fb0 chr_file 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 mdadm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Description of problem: I don't know. New install. I suspect logwatch might be the problem: Perl is now running "forever" in an unkillable (keeps respawning) process at 99% CPU.
