Hello,<br>
<br>
I continued testing and I verified that the SRS is set correctly (by
doing getfeature without bbox and only maxfeatures=10 in the call).
I also verified I am getting the correct data by this.<br>
No change with the max-features in the map-file. In the xml file it
seems to be needed.<br>
<br>
Best<br>
<br>

maxfeatures was my first guess... have you also turned ist it off (no
maxfeatures)?

<pre class="moz-quote-pre" wrap="">Dear All,
as this list is a source of much deeper insight than I have into
Mapserver, I would like to ask about a very strange issue I am facing.
I am calling on a public WFS server I can query "by hand" fast and
successfully every single time. Now I defined a Mapserver layer (see
below) as an OGR layer in my WFS map-file and it does - on the same call
- return data. But not reliably, more at random. I played with the
connection-timeout and the maxfeatures and it seemed to have some
influence but again, not reliably. I'll post the relevant parts of my
mapfile (all my other layers with other sources are working fine):

I made the xml-file wit ogrinfo as I did for many other layers that work.
The call is:

If I replace the Server name with the public server, it works like a
breeze (even it is 3857).
The public server has:
