You simply asking too much from the source you are trying to process:
If you'd try to process it without -z 0:18 you'll get max zoom at 10, which is
quite close the the rasters native resolution.
So when you're asking for max zoom 18 then GDAL is upscaling your source to
something quite enormous (you'll calculate it yourself;). This is quite
meaningless as your source cannot provide such a detail.
If you need some more control over automatic zoom range calculation you'd try
something like -z :+1, which in this case will give you max zoom of 11.

BTW you can also try something like --zoom=-1:+1 or --zoom=+2:-1
Undocumented, sorry, but you can call it an Easter Egg ;)
