When I replace the Global.asax file and use my site I get this error in the Event Logs:

S.Web Stopped CS.Web Stopped

_shutDownMessage=Change in GLOBAL.ASAX
Change in GLOBAL.ASAX

_shutDownStack= at System.Environment.GetStackTrace(Exception e)
at System.Environment.GetStackTrace(Exception e)
at System.Environment.get_StackTrace()
at System.Web.HttpRuntime.ShutdownAppDomain()
at System.Web.HttpApplicationFactory.OnAppFileChange(Object sender, FileChangeEvent e)
at System.Web.DirectoryMonitor.OnFileChange(FileAction action, String fileName)
at System.Web.DirMonCompletion.OnFileChange(FileAction action, String fileName)

This stops all the jobs from running.  It is only after I replace the Global.asax file with the original from CS that my site comes back to life.  Any idears about what is going on?  As it is now, I cannot use the chat on my site at all.

Thanks!
