Hi Bart Read this? (I had even MapServer crashing when using default on points): http://umn.mapserver.ch/MapServer/en/shapetree.htm, on the bottom:
SYNTAX: shptree <shpfile> [<depth>] <depth> (optional) is the maximum depth of the index to create, default is 0 meaning that shptree will calculate automatically the default depth (calculated so, that a quadtree cell contains 8 shapes). Do not use the default depth with point files, here a depth between 6 and 10 works fine.
