I am using vtl to do some hotspot analysis. For one of my application, the data collection phase was fine; but when I want to view the result (using "vtl view"), I got hundreds of lines of "Warning - runnning *really* short on DMA buffer", followed by the following message:
Thanks. It seems memory is the problem. I have 1GB RAM and 2GB swap space on my machine, but vtl eats them all without hesitation. Why viewing the result needs so much mamory? Is there any way to reduce the memory consumption, for example, working in a streaming mode?
