My application is shutting down and restarting multiple times continuously.  I contacted tech support and the response I received stated this is happening because of a service that was enabled on my site.

Does anyone know anything about this "service"?  Is this good for DNN?

Currently I am having a few issues of email notifications not going out and one member cannot log in.  Not sure if they are related but I was not having these issues before my event log was being filled up with the application cycling.

When this happens, my schedule is also taken down and restarted.

This is the message in the event log associated with the Application Shutdown:  The AppDomain shut down because of the hosting environment.

Any information will be appreciated.

Thanks.

You should also turn off Event Log Buffering as well.  If you have a recurring error and event log buffering the event log fills the available memory and can cause a app restart.
