延迟的作业多次运行同一个作业?

我已经用了一段时间没有问题的工作;主要用于排队ActionMailer调用(Notifier.send\u later…)。最近,它从同一份工作中随机发送多封电子邮件。我会把一封邮件排成队列,然后我会同时收到五次,或者一次,或者两次。我重新开始了我的工作,它似乎有一点表现。有人经历过吗?

这是我的日志;我以前从没见过这些错误。。。

当您部署应用程序的新版本时,请确保杀死所有DJ worker并只启动1个(或者不管您想要多少个-从1开始调试这个问题)。

ps -ef | grep delayed_job

我也遇到了同样的问题,当我检查我的队列时,我发现我在作业中有一个错误,DJ试图一次又一次地运行这个作业。
