I have an Umbraco site running 7.2.1 on 2 load balanced nodes sharing a file system on another server. Everything works well on my local machine and the first node. The second node, which should be identical to the first, has an issue whenever a view is invoking Umbraco.Media. The error points to the line with the Umbraco.Media call and says it's an IOException: An unexpected error occurred. This isn't terribly verbose and I'm not getting much out of the stack trace (included below).

Do anyone have any ideas or suggestiong for how to debug. Again, this only happens on the second server. All other pages (and the backoffice) work fine on this server except any pages with views that call Umbraco.Media.

var imageUrl = Umbraco.Media(il.GetValue<int>("image")).Url;

[IOException: An unexpected network error occurred.
