Try changing the buffer_size to reduce memory usage

--buffer_size [number]
  Sets the internal buffer size, corresponding to the number of variations that are read in to memory simultaneously. Set this lower to use less memory at the expense of longer run time, and higher to use more memory with a faster run time. Default = 5000
