Información adicional

The users code has a flaw in it, when exactly one geometry is returned (for example, no union). They are using a geometry from a recycling cursor after the cursor has been freed. The geometry’s memory is free, and in their code, some of the free memory is used in a way that causes the geometry’s spatial indexed to exhaust memory. In other cases, the freed memory is not manipulated in a way that causes the spatial index to react as it does in this case. This gives the distinctive “only in this application” behavior (although other memory configurations could yield other bad results).

Solución alternativa

The solution is to either use a non-recycling cursor, call get_ShapeCopy, or clone the shape in the case that they never union geometries. The non-recycling cursors causes the application to overall use more memory, same with get_shapeCopy. However the third option has the least impact to their existing code. To clone the shape in the case they detect that the union is not required, avoids the flaw in the coding pattern.
