Resolution

For Satellite 6.1 or newer:

If the problem appeared in Satellite 6.1 or newer, please open a support case to identify the root cause.

For Satellite 6.0:

There is a bug in Satellite causing this, which is fixed in Satellite 6.1. To prevent the issue from reoccurring, it is recommended to upgrade to Satellite 6.1. If that is not possible, the steps below serve as a workaround for the issue:

To workaround :

• First reboot the machine to force pulp to put everything in a paused state that is currently running. The reason for the reboot is there is currently a bug with restarting the katello-service and the workers not being released.

• Then get rid of the tasks:

# systemctl stop foreman-tasks

# foreman-rake console  #(let it load all the way)
ForemanTasks::Task.where(:state => :paused).where(:label => "Actions::Katello::Repository::Sync").destroy_all
ForemanTasks::Task.where(:state => :paused).where(:label => "Actions::Pulp::Consumer::GenerateApplicability").destroy_all
ForemanTasks::Task.where(:state => :paused).where(:label => "Actions::Katello::System::GenerateApplicability").destroy_all

# systemctl start foreman-tasks

This will kill all paused tasks.

• Install pulp-admin by following this solution

• Then run this script to make sure all pulp tasks are killed:

#!/bin/bash

pulpAdminPassword=$(grep ^default_password /etc/pulp/server.conf | cut -d' ' -f2)

STATE=""
for TASK in `pulp-admin -u admin -p $pulpAdminPassword tasks list | egrep '^Task Id:|^State:' | sed -e 's,^Task Id: ,,' -e 's,^State: ,,'`; do
        if [ "$STATE" = "" ]; then
                STATE=$TASK
        else
                if [ $STATE != Successful ] && [ $STATE != Cancelled ] && [ $STATE != Failed ]; then
                        pulp-admin -u admin -p $pulpAdminPassword tasks details --task-id=$TASK
                        pulp-admin -u admin -p $pulpAdminPassword tasks cancel --task-id=$TASK
                fi
                STATE=""
        fi
done

• Reboot again and then do the following to clear orphaned entries in katello database and reindex tables:

# foreman-rake katello:delete_orphaned_content --trace
# foreman-rake katello:reindex --trace
