API server hangs/breaks down during heavy load

Investigate root cause for why the development server breaks down during heavy load

@dk-teknologisk-mon Could you provide a short summary of the experienced issues and maybe a representative JSON file used (or similar to the ones used)?

Resolving #39 in #43 has most likely fixed this issue and no further investigation into causes will be done.
However, we need to verify this by stress testing the currently deployed "dev" version.
