Azure VM IIS 重新启动

Question

We have a simple .net application running crystal reports in an Azure VM. We have some code that detects if the application has restarted, and this application is restarting often.

protected void Application_Start()
{
    if (!HttpContext.Current.IsDebuggingEnabled)
        SendgridService.SendAppRestartEmail();        
}

I suspect the application is going to sleep or something is triggering the restart, but cant work out what.

After doing a lot of searching I am posting here to see if anyone can help

Most likely the problem is that your AppPool is getting recycled because of the low usage. You'll need to adjust timeout settings. See the following articles:
