Eu tenho um problema com este serviço do SystemD:
[unidade] Descrição = Serviços de Cliente RTC After = rds.service Requer = rds.service

A máquina arranca todas as manhãs. O serviço executa o ExecStart, mas de repente ele pára, enquanto tenta matar o processo PID:

Este é o script que o rtc_client.service lança:

O mais estranho é que, se eu iniciar o serviço ou reiniciar a máquina durante o dia, o serviço será iniciado e permanecerá ativo ...

Qualquer ajuda é muito apreciada!
A razão pela qual seu serviço está parando está no log que você forneceu:
/bin/bash rtc_client.sh start (code=exited, status=0/SUCCESS)
Seu script rtc_client.sh está saindo com um status SUCESSO. Você deve investigar seu script para ver por que ele não continua funcionando continuamente.
