Sounds like a driver and/or X issue, or maybe simply that you stress the 
memory subsystem too much. (If you run out of RAM, and especially if you 
run out of swap space, some kernels don't behave too well. It may take a 
good while before the kernel gets around to deal with the situation - 
although at that point, you would normally notice that some process is 
killed...)

Are you seeing this with other applications? Any certain feature that 
seems to trigger it? Tried any other driver version, library or X 
versions? Are you sure you don't have mixed versions of some stuff? Tried 
your program on another machine?
