Seeing spikes or DEE errors too with my HRD app recently, while it has been right for several months.
Reminds me of the symptoms seen when we used M/S: suddenly a burst of DEE and many instances gets killed, with these two logging messages: I 2011-12-08 13:03:35.164 This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application. W 2011-12-08 13:03:35.164 A serious problem was encountered with the process that handled this request, causing it to exit. This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you may be throwing exceptions during the initialization of your application.
