unit.service перестал работать потому что процесс управления, из которого выходят с кодом ошибки. Что означает эта ошибка?

Я пытаюсь запустить сценарий в /etc/init.d в ubuntu 16.04. но это дает мне ошибку. Я могу выполнить каждый шаг в этом (scheduler_slave) единица вручную. Однако это перестало работать при выполнении через сценарий.

Мог любой объяснять, что является значением ниже ошибки /

Я - полностью новичок к этому полю и пытающийся выяснить, почему эта ошибка прибывает. Сообщите мне, пропустил ли я какую-либо деталь.

команда:

sudo /etc/init.d/scheduler_slave start
