Multiprocessing is throwing this error when dealing with large amounts of data (all floating points an integers), but none of which exceeds the number boundaries in the error that it throws:

  File "/root/anaconda3/lib/python3.5/multiprocessing/", line 268, in starmap
    return self._map_async(func, iterable, starmapstar, chunksize).get()
  File "/root/anaconda3/lib/python3.5/multiprocessing/", line 608, in get
    raise self._value
  File "/root/anaconda3/lib/python3.5/multiprocessing/", line 385, in _handle_tasks
  File "/root/anaconda3/lib/python3.5/multiprocessing/", line 206, in send
  File "/root/anaconda3/lib/python3.5/multiprocessing/", line 393, in _send_bytes
    header = struct.pack("!i", n)
struct.error: 'i' format requires -2147483648 <= number <= 2147483647
> /root/anaconda3/lib/python3.5/multiprocessing/
-> header = struct.pack("!i", n)

It works fine on any number of subsets of this data, but not when put together.
