Chad,
     You are running the IDV with the default memory 512m, and this doesn't 
look big enough when you are trying to open 20 high resolution radar datasets, 
even though you only open one sweep per dataset, which is about 720*1830*20 
points, and total is about 844m in memory. In our FAQ, there is a tip about 
increase the memory: 
"http://www.unidata.ucar.edu/software/idv/docs/userguide/Faq.html#memory";, but 
I also notice that you only have 1.25G in the RAM, so, you need to consider to 
reduce the amount of dataset loaded in the IDV.
