application_start意外触发了asp.net

我正在查看一个asp.net应用程序,该应用程序调用应用程序中的数据库在global.asax中启动.这些调用大约需要3秒钟(取决于SQL缓存计划)才能运行.我注意到第一次重新部署时应用程序运行缓慢.我把它放在应用程序启动时对数据库的调用.但是几分钟后,应用程序再次需要时间来加载.

为了弄清楚发生了什么,我写了一个日志文件(见下文).从这个文件中你可以看到,当多个请求第一次到达应用程序时,应用程序启动多次.然后看起来application_start以随机方式触发(任何时间为2-10分钟).

根据我对application_starts如何工作的理解,它应该只在应用程序FIRST启动时被触发,但它似乎是从多个客户端随机触发的！根据MSDN“应用程序启动时第一次触发Application_Start事件.”

任何人都可以帮我解决发生的事情吗？我正在使用IIS6和.net 2.0.它是我缺少的应用程序池设置.

非常感谢
Rippo
