Ok, finally found some time to look into this. I can confirm this is an issue happening on windows only, the memory mapping failed to be disabled according to configuration I fixed it, but not in time for beta3. However I've attached fixed shapefile store jar which should work as a replacement for the one in beta3 here: http://jira.codehaus.org/browse/GEOS-4268 Past the patch I tried to display a 4.5GB (total, shp + dbf) shapefile which was part of the FOSS4G 2010 exercise on windows and had no issues Cheers Andrea ----------------------------------------------------- Ing.
