Does cygwin reside the same partition as XP? Try to let the system administer the swap space. Alternatively, increase swap to 2 GB.
On my WinXP machine (1.7 Dothan, 1GB physical RAM) this eventually helped. 
Best regards-
Andreas

	First, thanks for getting back to me.
	
	I upgraded the machine to 1 GB of physical RAM and 1.5 GB of swap space
	(with an additional 3 GB of free space left on the drive). I reran the FEEDS
	test suite and am still getting the same error (see below). Is there a way
	to show that this is a memory problem? (I do not see any errors saying that
	I am running low on virtual memory.)
	
	I appreciate your help,

	Hi Bennett-
	
	this is related to deficient memory preventing the generation of skull +
	scalp surface images.
	Increase virtual memory of let the system administer its size. That should
	do it - at least if you have a minimum of 1GB physical RAM.
	Best regards-
	Andreas

	        Good morning,
	       
	        My FEEDS validation suite is failing for the BET2 surfaces under
	winXP.
	        (Full feeds output included below.) I also installed the complete
	cygwin
	        kit (as per the last message on this topic), but the problem
	persists. I'd
	        very much appreciate any help setting up FSL under winXP.
	       
	        Thanks,
	        Bennett Landman
