You need to cleanup the resource: crm resource cleanup RTWeb
Otherwise, I really cannot say what's wrong with your apache, but
it's definitely resource specific. You can leave out the cluster
and try to resolve the issue using ocf-tester. Also, it is
necessary that the apache status module is enabled.
