Hi all,

I am working on Umbraco v7.2.4. I have a surface controller that has an action that loops over all documents of a certain type and does stuff (generate a text file).

Here is my code in its most simple form:

public class DataImportController : SurfaceController
{

    public string Test()
    {
        var cs = new ContentService();
        var allItems = cs.GetContentOfContentType(1145);
        return "ok";
    }
}

This runs fine on my local site and on the staging server for any document type. But on the live server, it always causes a Service Unavailable message (but doesn't take the whole site down) for a particular document type (news article).

I'm at a loss as to how to proceed. Is this a data issue, and if so, how can I find out which node is causing the problem?

Any ideas to try?

Thanks,

David
