Hi guys,

I have two sites on IIS 8, i often get an error like as:

DotNetNuke.Common.Initialize - The connection to the database has failed, however, the application is already completely installed, a 500 error page will be shown to visitors

My app is running about 4hours, it will die. so after that restart server and iis,it's working again.

Please tell me reason and resolve it.

Thank you in advance
