"Error 999999: Coordinate limit exceeded", this error can be seen in many different ways for different coordinate types (Z or M) including:
"Error 999999: Invalid topology z coordinate limit exceeded"
"Error 999999: Z coordinate limit exceeded"
This error is often caused when running geoprocessing or data management tools. The reason is due to the processing of the tool creating a vertex that is outside of the spatial domain set in the feature class. Unlike a feature extent, the spatial domain cannot be changed and is set when the feature class is created.
The error can also be caused by low-precision feature classes or datasets created prior to ArcGIS version 9.2.
To work around this issue there are a few different options including migration to a new format, disabling Z or M coordinates, or creating a new feature class. The best option is to create a new feature class with a larger domain.
