Question

我使用AWS Beanstealk php worker环境。

我在cron.yaml管理我的cron工作

version: 1
cron:
 - name: "prepare-technical"
   url: "/workers/cron/event/prepare/technical"
   schedule: "45 0 * * *"

我并不明白为什么，但是，这个cron执行了两次并且在不同的时间内执行：

127.0.0.1 (-) - - [24/Mar/2017:00:44:59 +0000] "POST /workers/cron/event/prepare/technical HTTP/1.1" 200 - "-" "aws-sqsd/2.3"

你知道我该如何解决这个问题？感谢

默认情况下，如果您的网络服务器在五分钟内没有响应，则会重新发布作业。有几种可能的方法：

1）增加Configuration / Worker Configuration / Advanced Options下的“Inactivity Timeout”。最大值为1800（30分钟）。

2）通过添加处理能力或将它们分成更小的块来使作业更快地运行。

3）当你收到一份工作时，在后台线程中执行它并立即从主线程返回。
