I am getting a MemoryError from a numpy.fromfile() call in an application I am trying to deploy. Normally I would assume that this would mean that I don't have enough memory available on the system.

If you are on a 32-bit platform, the maximum addressable memory for a single process is limited to 3 GB, and what can be allocated can be less than this because of memory fragmentation. Also, you should check that you don't have an ulimit set for virtual/RSS memory.
