[QGIS-Developer] QGIS Server WFS 2.18 unreliable?

Hi René and David, 

Thank you for your replies. Interesting to see that GeoJSON works, but
GMLv3 fails. 

In my Apache webserver log I find the following error: 

[Wed Nov 14 14:32:54.580958 2018] [fcgid:error] [pid 13453] mod_fcgid:
process /var/www/cgi-bin/qgis_mapserv.fcgi(22829) exit(communication
error), get unexpected signal 11 

I also checked the geometries of the concenred table in Postgis for
validity. All geometries seem to be valid. 

Do you have any idea what I could do? Or do you think the issue will be
solved in QGIS 3.x master? 

Thanks, 

Andreas
