Since an aperture is usually associated with a pin or pad definition,
it's likely that your footprints use many different pad diameters,
ring radii, hole sizes, etc.  Accordingly, you can also address your
problem by editing all your footprints and harmonising the pin and
pad definitions.

Shameless plug for gerbv:  Take a look at your Gerbers in gerbv, and
use the window available under the "analysis" menu item to look at all
the apertures you have defined.  I'll bet you have lots of slightly
different, but similarly-sized apertures.
