It could be that you updated a shapefile without updating the spatial
index. Check your data folder and look for a qix file with the same
name as your shapefile. If the date is older than your shapefile you
will either need to delete it, or update it using shptree <a href="http://mapserver.org/utilities/shptree.html" target="_blank">http://mapserver.org/<wbr>utilities/shptree.html</a>.<br>

> Hey,<br>
> i'm using Mapserver 6.0.2. I have a layer containing a lot of polygons. In the<br>
> first zoom stage all features are fine. But if I zoom in: more and more<br>
> features disappear randomly. While panning some features appear again but<br>
> others disappear.<br>
><br>
><br>
> I found some remarks to that problem:<br>
><br>
> I read something about 'features with too much vertices disappear' (but not<br>
> in context of mapserver) - this is not the reason, because also small polygons<br>
> disappear while bigger ones are displayed.<br>
> Another problem is if some points of the polygon are outside of the current<br>
> map extent. That's also not the case - in my map features in the center<br>
> disappear, too.<br>
><br>
> Are there any other suggestions?<br>
