Ruby on rails systemu-执行已过期

我正在延迟的作业进程中运行systemu。我的作业失败，并在我的delayed_jobs表中发现此错误：

它以前工作得很好，但这是我正在做的一项更大的工作。是否需要设置一些超时

---

谢谢

好的问题是延迟的作业超时。我不得不在规定的时间内：

Delayed::Worker.max_run_time = 48.hours #2 days

---

在app/config/initializers/delayed_job_config.rb

OK中，问题是延迟的_job超时。我不得不在规定的时间内：

Delayed::Worker.max_run_time = 48.hours #2 days

在app/config/initializers/delayed_job_config.rb中
