pulp-server-2.13.4-1.el7sat.noarch

Steps to verify:
1. All workers (0-7) are using --maxtasksperchild option
# grep ^PULP_MAX_TASKS_PER_CHILD /etc/default/pulp_workers
PULP_MAX_TASKS_PER_CHILD=2

# ps -axu | grep -c maxtasksperchild=[2] 
16

2. Customize PULP_MAX_TASKS_PER_CHILD option using installer option --katello-max-tasks-per-pulp-worker
# satellite-installer --katello-max-tasks-per-pulp-worker 3
Installing             Done                                               [100%] [...............]
  Success!
  * Satellite is running at https://satellite
  * To install an additional Capsule on separate machine continue by running:

      capsule-certs-generate --foreman-proxy-fqdn "$CAPSULE" --certs-tar "/root/$CAPSULE-certs.tar"
  The full log is at /var/log/foreman-installer/satellite.log

# katello-service restart

# grep ^PULP_MAX_TASKS_PER_CHILD /etc/default/pulp_workers
PULP_MAX_TASKS_PER_CHILD=3

# ps -axu | grep -c maxtasksperchild=[3] 
16

3. Reset PULP_MAX_TASKS_PER_CHILD value using installer option --reset-katello-max-tasks-per-pulp-worker
# satellite-installer --reset-katello-max-tasks-per-pulp-worker
Installing             Done                                               [100%] [.............................]
  Success!
  * Satellite is running at https://satellite
  * To install an additional Capsule on separate machine continue by running:

      capsule-certs-generate --foreman-proxy-fqdn "$CAPSULE" --certs-tar "/root/$CAPSULE-certs.tar"
  The full log is at /var/log/foreman-installer/satellite.log


# katello-service restart
# grep ^PULP_MAX_TASKS_PER_CHILD /etc/default/pulp_workers
PULP_MAX_TASKS_PER_CHILD=2
# ps -axu | grep -c maxtasksperchild=[2] 
16

4. Undefining PULP_MAX_TASKS_PER_CHILD as in bug 1388631, comment 20 is not possible, because --katello-max-tasks-per-pulp-worker requires integer value. IMO this is not an issue.
