      Hi
      
      
      Every so often I see the following in my logs.  A response code of 500, a warning to the effect the instance has crashed, and an error 204 in the log.
      I am running Python 2.7 with threading on.  So it seems occasionally the same instance is handling multiple requests when the error occurrs
      affecting multiple requests,  I also get this type of error on warmup requests. These requests fail in a short period, so no timeout's DEE's etc appear
      to be involved.
      
      
      Unfortunately the complete lack of information from the log does not allow any form of diagnosis.  My assumption is it's a runtime failure of python etc,,
      Anyone got any ideas?

      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.

      A 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. (Error code 204)

Hi,

This does appear to be an issue with the runtime. We are aware of it and are looking to push out a fix in the near future.

Can you email me privately the app id? Thanks.
