Hi Sevket, For large paged database you'll need to use vpbmaster to create a set of tasks that sub-divide down the database generation so that each individual run of osgdem task will be small enough to avoid memory issues. vpbmaster will allow you to use multiple CPU's on one machine and a cluster of machines.
