Ruby on rails 延迟作业：延迟作业任务挂起

我正在使用延迟作业来执行后台作业。我正在使用命令

RAILS\u ENV=production bin/delayed\u job-n 5 start运行延迟作业

当我启动延迟作业并检查延迟作业时，它显示作业正在运行。当我在1小时后再次检查延迟作业时，所有作业的延迟作业状态仍为“正在运行”。所有作业本应在15分钟内完成，但即使在1小时后，其状态仍显示为正在运行。请帮忙

下面是我的延迟作业日志文件内容

正在运行的作业的状态如下所示

我想你已经把工作安排在别的地方了。因此，问题在于为什么作业一直在运行

我认为您应该首先确保流程确实已启动

然后，gem是一个有用的接口，用于监视进程的状态

另一方面，您可以尝试设置

max_run_time

，以查看

delayed_job

是否按预期运行

# config/initializers/delayed_job_config.rb
Delayed::Worker.max_run_time = 5.minutes
