On Red Hat Satellite 6 Red Hat Repository selection hangs indefinitely on certain products.

Environment

• Red Hat Satellite 6.x

Issue

• When drilling down on certain products on the Enable Red Hat Repositories page, the spinner will not stop and the Actions::Katello::Repository::ScanCdn task goes into a running state indefinitely.

Resolution

• Try to confirm whether there are any connection related issues,confirm that satellite is able to reach out to cdn.redhat.com without any issue.
• If satellite server is behind http proxy check for network connectivity.
• Once it's confirm that there are no network related issue,you can go ahead and try to clear any existing Actions::Katello::Repository::ScanCdn task which is stuck in paused state by following this commands:

# service foreman-tasks stop
# foreman-rake console

ForemanTasks::Task.where(:label => "Actions::Katello::RepositorySet::ScanCdn", :state => "paused").map { |task| task.update_column(:state, "stopped") }

If there is any `running` state task for the same task lets stop the same by running:

ForemanTasks::Task.where(:label => "Actions::Katello::RepositorySet::ScanCdn", :state => "running").map { |task| task.update_column(:state, "stopped") }

# service foreman-tasks start 

• After the above commands executed try to run the below command to restart pulp related services:

   # for i in pulp_celerybeat pulp_resource_manager pulp_workers; do service $i stop; done
   # for i in pulp_celerybeat pulp_resource_manager pulp_workers; do service $i start; done

Now confirm that all the services are up and running:

   # hammer ping
   # katello-service status

• Once the services are up,again try to enable the repositories.
