Memory leak in orders app

Overview:
I've been trying to load our approximately 50,000 orders and I'm having problems. I keep getting an out of memory error with a giant memory dump at the end of the log. I've tried increasing the Docker max memory size all the way up to 32 GB, but, it still bombs out at around 39,300 orders loaded. There seems to be a memory leak or something. Also, it seems to take somewhat randomly long periods of time before it gets to that point. One run took 4 hours 14 minutes. Another took 5 and a half hours. And another took over 8 hours. Also, it seemed to not be able to convert currency TWD (New Taiwan dollar).

Steps to Reproduce:

1. Load a large order data set

Expected Results: Orders are created successfully

Actual Results: Out of memory error occurs
