When using secure ArcGIS Online services, we've been noticing seemingly random cases where the layer initialization fails due to a WebException, noting that "the server committed a protocol violation". It's not terribly frequent (about 1 out of 20 times) - and it doesn't happen outside of secure ArcGIS Online services. Has anyone else seen this? The unhandled exception is below:System.Net.WebException: The server committed a protocol violation.
