To elaborate a bit more... The program "strace" is invaluable for 
finding out what a program is doing (or failing to do). If you strace 
your program's execution (and the failure is happening early enough) 
then you can probably find out which fopen() is failing and why.

Like I said, this may be due to a VE issue (too many FDs open already, 
out of memory while reading file, etc) or may be something about the 
program itself.
