Every now and then after startup the deployment is left in state resulting in the following error for mostly all requests:
SWITCHYARD035408: Failed to map context properties to SOAP message

The stack trace for the error is:

I browsed through SOAPContextMapper and the base class sources but the exact cause is not clear. This error happens intermittently at startup but is persistent afterwards.
