I have a machine with 1.5Gb of physical memory, and have for a long 
time used --max-mem-size 2G, 
without any problems. Just yesterday that wasn't enough, so I tried 
to increase to --max-mem-size 4G, which was rejected by R. 
I lowered to 3G, and the program seemt to be running fine, but 
eventually I had to kill the process (hanging). 

This is windows XP professional. So, at least on XP, there is 
certainly not a hard coded limit of 1G. But why the limit somewhere 
between 3 and 4G?

Have others had problems with R processes eventually hanging on XP, 
if using more than 2G og memory?
