Problem: ArcGIS Desktop crashes when using the Align Edge tool


ArcGIS Desktop crashes when using the Align Edge tool in topology editing. This occurs when aligning a topology edge in the map and clicking save afterward with no error messages appearing.


This issue may occur due to limited space on the server or local disk.

Turn off the layers not required for editing while using the Align Edge tool

To turn off the unnecessary layers, navigate to the Contents pane in ArcGIS Pro or navigate to the Table of Contents pane in ArcMap, and uncheck the check box next to the layer's name.

For ArcMap, use classic snapping to avoid selecting all layers at once to save more disk space. Refer to ArcMap: Enabling snapping (classic snapping) for more information.
