Add the following code to the Sitefinity project's global.asax.cs file:

var err = ((HttpApplication)sender).Server.GetLastError();

if ((err is ArgumentOutOfRangeException) && err.Message.StartsWith("Type is enhanced and registered"))

{

var strBuilder = new StringBuilder();

strBuilder.AppendFormat("Details regarding '{0}'", err.Message);

strBuilder.AppendLine();

var connectionsField = (typeof

(OpenAccessConnection)).GetFields(System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.NonPublic).FirstOrDefault(f => f.Name ==

"connections");

if (connectionsField != null)

{

var connections = connectionsField.GetValue(null) as IDictionary<string, OpenAccessConnection>;

foreach (var connection in connections.Values)

{

strBuilder.AppendFormat("Connection: {0} / {1}", connection.Name, connection.ConnectionString);

strBuilder.AppendLine();

var databaseField = (typeof

(OpenAccessConnection)).GetFields(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).FirstOrDefault(f => f.Name ==

"currentDatabase");

if (databaseField != null)

{

var database = databaseField.GetValue(connection) as Database;

strBuilder.AppendFormat("Registered meta types: {0}", string.Join("; ", database.MetaData.PersistentTypes.Select(t => t.FullName)));

strBuilder.AppendLine();

}

var field = (typeof

(OpenAccessConnection)).GetFields(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).FirstOrDefault(f => f.Name ==

"registeredModules");

if (field != null)

{

strBuilder.AppendFormat("Registered modules: {0}", string.Join("; ", ((HashSet<string>)field.GetValue(connection)).ToArray()));

strBuilder.AppendLine();

}

strBuilder.AppendLine("------------");

}

Log.Write(strBuilder.ToString(), System.Diagnostics.TraceEventType.Information);

}

Once the error happens again, send the Trace.log file (from the project's App_Data\Sitefinity\Logs\ folder) to Sitefinity Technical Support.
