SharePoint功能收缩会杀死应用程序池

本周早些时候，我公司的解决方案设计师最近向所有开发人员发出了一个挑战，要求他们找到他编写的一些代码中的错误。发生的事情是，当一些问题出现时，构建管理员从SharePoint撤回了他的解决方案包，整个应用程序池都死了。

据推测，原因是以下之一:

代码中的内容
• 是否与从中央管理部门撤回解决方案有关?
• C -以上都不是
• D -以上所有

我今天一直在看代码，但没有发现任何问题。我想我应该把他的代码放在这里，并从任何有兴趣给出一个的人那里得到一个意见。这不是一个严肃的问题，这个挑战是出于善意，所以如果你愿意的话，请给予它任何关注。

来自SD的消息:

正如我昨天在DevDays中提到的，当SharePoint管理员从SharePoint中收回CityDepartments解决方案包时，整个IIS应用程序池就死了。这是在owtimer . exe计时器作业可以解锁所有它锁定的Web应用程序和网站之前，在实际功能被停用之前。

所以，既然没有人知道哪里出了问题，我将奖励第一个找出问题的人(包括我自己)。

正如我所承诺的，如果你能在一个功能失效事件中发现问题，导致SharePoint崩溃，就像上周发生的那样，那么我将给你买两张电影票，看目前正在放映的任何一部NuMetro或SterKinekor电影。证据将是在DEV和QA环境中成功部署和收回固定的解决方案包(3次只是为了确保)。
