It froze again this morning.  I received this SELinux error:

SELinux is preventing abrt-action-sav from write access on the file /var/lib/rpm/.dbenv.lock.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label.
/var/lib/rpm/.dbenv.lock default label should be rpm_var_lib_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
# /sbin/restorecon -v /var/lib/rpm/.dbenv.lock

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that abrt-action-sav should be allowed write access on the .dbenv.lock file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'abrt-action-sav' --raw | audit2allow -M my-abrtactionsav
# semodule -X 300 -i my-abrtactionsav.pp
