We have occasional server shutdowns on the machine hosting both map/feature services and GeoEvent Extentsion. Sometimes planned, sometimes not so much. These shutdowns absolutely destroy our GeoEvent services, to the point where I have to publish new map/feature services and re-configure the existing GeoEvent services to use these new services. I have tried 'graceful' shutdowns - shutting down the GeoEvent Service, then input+output connectors, then GeoEvent Service as a whole, then ArcServer, and bringing them back up manually in the reverse order) - no luck, things are still completely busted.
Is there a way to handle this kind of thing? It's pretty disruptive and frustrating.
