Ruby on rails Sidekiq服务似乎是'；睡眠'；，当与交互时唤醒

所以，我很难理解为什么Sidekiq会这样。我使用以下sidekiq.service在启动时启用sidekiq（从）：

一切似乎都很好。该服务处于活动状态并已启用，没有错误。然而，过了一段时间，它似乎去了。。。睡觉遵守以下命令：

通过systemctl查看状态后，Sidekiq神奇地复活了。这是不应该发生的，因为我希望Sidekiq能一直听。另一个例子是，当Sidekiq在grepping后复活时（您甚至可以看到第二个命令后Sidekiq复活）：

我真的不知道为什么会发生这种情况，也不知道为什么Sidekiq会“睡觉”。我使用的是Ubuntu18.04.2 LTS。

也许它正在崩溃，systemd正在重新启动它？查看日志。@jan-hoi您是否找到导致此问题的原因？
