We are running multible ArcGIS Servers 10.9.1 and one of them startet to go under heavy load by an arcsoc process "arcgis-geoanalytics-ex" running in up to four instances. The Load was so heavy none of our mapservices could respond. Over about 20-30 Minutes. After that one instance remained at 0% load.
see attached screenshot
We could not find any service that is configured that way. Geoanalytics service was and is stopped on this service.
Can someone please give us some insights what this arcsoc process is doing and how to prevent it from causing such heavy load.
