I generated contour lines for my working area with GDAL based on SRTM data, which worked quite fine and looks really good. At the very beginning the contour shapefile had a size of > 3,5 GB, which was quite to heavy for GeoServer to deal with. Thus, (1) I first splittet the contour shapefile content-realted into 3 separate shapefiles with an average size of 1,2 GB, (2) then I loaded them into my PostGIS-DB and (3) finally published them in GeoServer. Up to here, everything works fine. But when I now try to render one of the three conour shapfile separately with GeoServer, nothing happens. Even though when I try to SEED tiles using the GeoWebCache (GWC) - only white tiles will be created. And when I add a single contor shapefile to my LAYERGROUP, nothing happens aswell. In comparison, without the contour shapefile my LAYERGROUP works fine. What happened? Is GeoServer not able to work with (contour) shapefile bigger than a distinct amount - maybe bigger than 1GB? Because, when I am working with a subset of the contour shapefile (approx. 700MB) everything works fine! Has someone an idea what happens/happend and how to avoid this problem - some solutions/ideas?
You may want to switch to PostGIS and look at smoothing / simplifying some of the geometry prior to use.
GeoServer may also be struggling to produce the initial spatial index (QNX) file prior to rendering - have a look and see if it has been generated.
