SharePoint down every morning

I'm not 100% sure if this is related to your tool or not, but I've been using this for a while now and it's been amazing. Thank you for sharing it.
However, the past few weeks, we've been running into a problem where SharePoint will not work. Every morning between 2:30 and 2:45 AM something happens and the users can login and authenticate, but when they do it throws up an error page. Here is the error we get:

Go back to site

Value cannot be null.
Parameter name: value at System.String.EndsWith(String value, StringComparison comparisonType)
at Microsoft.SharePoint.ApplicationRuntime.SPRequestModule.PostAuthenticateRequestHandler(Object oSender, EventArgs ea)
at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Troubleshoot issues with Windows SharePoint Services.

IISreset fixes the issue in no time, but it comes back every day. Any thoughts?

See disposing SharePoint resources issue on this project, we have the same problems on our farm.

We actually got this working ok now that we've moved to a new server.

Although, it appears that alerts are not working for users that are simply added to a role which is then added to a SharePoint group. If a user is manually added to the group alerts work fine, however, if a user is only in a role, it does not work. Would your issue "disposing Sharepoint" possibly help to address this?
