ArcGIS runs out of memory while labeling with Maplex.
Labeling can be a memory intensive process as the positions of hundreds or thousands of pieces of text are determined by the label engine.
The ESRI Maplex Label Engine allocates memory on an as needed basis during the labeling process. If necessary, the label engine will use all available physical memory during a labeling process.
Due to performance reasons, no paging to virtual memory is performed during labeling with the ESRI Maplex Label Engine.
The amount of memory used depends on a number of items including:
· The number of features being labeled.
· The extent of the map being labeled.
· The number of trial positions generated based on the label placement properties.
If memory usage issues are encountered while labeling with Maplex, try reducing one of the above parameters.
