[mapserver-users] MapServer crash with WFS GetFeature request using multiple typenames

Mon Nov 14 05:20:15 PST 2011

Hi,

It is not so very common to make GetFeature requests for a list of FeatureTypes, especially with filters. Therefore servers are for sure not well tested with such requests. Do you have some special need for getting just one GML package out or WFS or can you imagine to do one request per feature type?

By the way, are you aware of that if you query typeNames "A" and "B" with maxfeatures=10, the resultset will be cut at the 10th feature. If the server finds 10 or more candidates from typeName "A" you will not get any features at all from typeName "B".
