Multiple Connections On App INIT #9318

Hi, i have a critical problem with sql connections when the applications starts. The application works fine but when i want to publish some new changes, y do iisreset and when starts again, the framework begins to open multiple connections, and the application takes a long time to respond. Genereating multiple errors.

Did anyone have a similar problem?
