- Navigate to the ArcGIS Server Administrator API and restart the DynamicMappingHost service to resolve the issue.
- Adjust the number of shared instances per machine in ArcGIS Server Manager by navigating to Site > Settings > Pooling to resolve the issue, as this restarts the DynamicMappingHost service.
