Issue with buffering

Question

I find typical issue of overlapping for polygon buffering at times it fails.

Problem can be solved by splitting them into different polygons for which tools are available and combining later, but why at all it should fail. It amazed me such trivial thing can be bothering.

Check Geometryonly applies to non SDE data sources which are handled separately as for topology, that would be handled by ArcMap during the construction or change process

Hello,

Before doing geometrical operation on features , make sure features  don't have any topological  error,

Check and correct them.
Also consider above Dan points.

Besides geometry errors (which should be checked as a matter of procedure), consider a polygon with multiple holes/donuts and a concave convoluted shape... buffer such features may necessitate the removal of a portion or all of some of the geometry elements (ie the holes).  If overlaps are involved, this can cause issues, although you indicate that the geometries were kept separate and not dissolved.
