30005: Group layer is empty

You have an empty group layer in your map, which can affect performance.

Solution

• First, check the drawing performance of your map service in the Preview window. See Publishing map services for more information. If you see the need to make changes, remove the empty group layer from your map.

More information

Group layers are used to organize contents in your map. Two scenarios help illustrate the use of group layers:

• Organizing your information thematically (for example, to group all the hydrology layers or parcel layers together).
• Grouping map layers by their map scale, where each map scale has a different view that contains only the information relevant for use at that map scale. This technique is used for creating high-performance cached basemap services like those found at ArcGIS Online.
