We have a geoserver 2.7.1 running as a war on tomcat7 in a Ubuntu 14.04 box. When asking for a WMS we get a java.lang.NullPointerException, but only when the map window is above certain size and only on a specific Geoserver layer.
A request like this works fine:
A request like this also works fine:
But this request brings back an xml with a nullPointerException:
This layer is using a transformation style to produce a Heatmap. That, and the fact that only changing the size of the image requested makes it crash, would make me think about memory issues. But I have upped the max rendering memory of the WMS in Geoserver to 1048576 with the same results.
Also, if I ask for a tiled image I get no error, but the tiling of a heatmap layer does not produce good results.
Any ideas on how to fix this?
The geoserver log of the failing request says:
