Cadence 17.4 S019 has shorts appearing on copper pours

tmd63

I have an inner layer which is a ground plane and there are microvias going through this.

But when I check the copper pour. It has shorted out some pins! There is no DRC error I and would have to search 4000+ connections to see if the plane has shorted.

I must use a hatch plane. a solid plane does not short but it is a requirement of the design.

    Instead of using a hatch plane, could you use a solid plane with a matrix pattern of voids like the image below?

    The problem with this how would you set each via as to not have undercuts? How would you set the area to cover a PWB that is 14 inches long and 1.75 inches wide but avoid all through pins and vias? This is where a hatched shape performs greatly, normally!
