COMException Exception message: The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))

I deploy a web application in Production Server. In Production we are using Windows Server 2012, IIS 8.5. Deploying the application was successful but I got the error after 2-3 hours or 1 day from deploying the web application.
