Alguns servidores que eu atualizei recentemente para o Debian 9 agora produzem uma mensagem estranha de syslog todos os dias (que foi reportada via logcheck):
Oct 27 06:25:08 foo systemd[1]: [email protected]: Killing process 12270 (kill) with signal SIGKILL.
O tempo parece ser o de cron.daily e o nome do serviço se parece com o UID de nobody / nogroup mas por que ele morreu e o que ele estava fazendo em primeiro lugar?
Mais linhas de syslog nessa época. Esse bloco se repete algumas vezes:
