A minimalistic alternative is array.tofile()/fromfile(), but pickle should handle a list, say, of 5 million floating point numbers just fine. What exactly are you doing to provoke a crash, and what does it look like? Please give minimal code and the traceback. Peter -- http://mail.python.org/mailman/listinfo/python-list
