Hi, I confirm.
There is a layer limit in QGIS-Server I do a huge test removing one by one all the layers from my project. And after the removing of every single layer I retest the working. Aftr a while of time. I reach the limit. And the project begin to run. I do other test to exclude that was the number of layer inside a single group. All the test give the response that seem to be the max number of layers in a project. So the question is: QGIS desktop allow to put more layers rather than how many are accepted from qgis-server. This not good for a WYSIWYG system. Ok, I will try to patch my server when found exactly where is the problem. Meanwhile, Now the question is on what structure is this limit ? I don't guess it is simply a layer limit but perhaps a more specific structure. Now I have a project that crash , and a project with a one less layer that work. Doing a DIFF beetween the two projects I see the possible structure breakable are: layer-tree-canvas -> custom-order -> item maplayer Digitizing -> LayerSnappingList -> value (type QStringList) Digitizing -> LayerSnappingEnabledList -> value (type QStringList) Digitizing -> LayerSnapToList -> value (type QStringList) Digitizing -> LayerSnappingToleranceList -> value (type QStringList) I check if in the code there is a limited array dimension for this objects.
