Hi,

I try to generate a big (750 GB) database with VPB 0.9.10 & OSG 2.8.2 under 
kubuntu 8.04 (32 bit).

Unfortunately it seems to be too big, even Linux crashes (windows crashed even 
in quite small databases, therefor I use only Linux for Database generation).

The crash it self is a failure of sereval osgdem-tasks, always any subsubsub 
lib (sometimes of gdal, often libxbc.so ) of osgdem crashes and causes a 
segfault in that task. At the end of the run, nearly 30000 of 75000 tasks are 
not completed. 

Is it possible to re-run the vpbmaster call to only processes the uncompleted 
tasks? 

Are there any reasons why so much of my osgdem tasks fail? They fail local as 
well as on remote machines (cluster usage) .

can ulimits be the reason? which values do I have to rise? Of couse open files 
- anything else?


I hope anyone can give me useful hints.


Thank you in advance,
Torben
