MemoryError when Running Parking Location

@anneku and I both have gotten a memory error in the parking location model while running the resident model. The error message I'm getting is as follows:

The 3.4 billion number is the product of the number of choosers on that thread and the number of alternatives. Do we need to reduce those numbers, or is it a bug in the ActivitySim code itself?
