Question

我一直在使用delayed_job一段时间没有问题;主要用于排队ActionMailer调用（Notifier.send_later ...）。最近，它发出来自同一作业的随机多个电子邮件。我将排队一封电子邮件，我将同时收到五次，或一次或两次。我重新启动了delayed_job，它似乎表现得有点。有人经历过这个吗？

这是我的日志;我以前从未见过这些错误......

Answer 1

当您部署新版本的应用程序时，请确保终止所有DJ工作人员，并且只启动1（或者您想要的多少 - 从1开始调试此问题）。

ps -ef | grep delayed_job

Answer 2

我遇到了同样的问题，当我查看我的队列时，我发现我在工作中遇到错误而且DJ正试图一次又一次地运行这个工作。

Delayed_job多次运行相同的工作？
