Significant RAM Increase when increasing scheduler threads

Hello, I have been trying to use the DHS Paper plugin (the snapshot 0.9.0 version) and have been having a rough time getting it running properly... I used to think our server was really beefy and powerful, but this plugin has began to make me reconsider my opinion haha The configuration entries that might be applicable here are: 
distant_generation_enabled: true
generate_new_chunks: false
builder_type: FastOverworldBuilder
builder_resolution: 2
scheduler_threads: 4
distant_generation_enabled: true
generate_new_chunks: false
builder_type: FastOverworldBuilder
builder_resolution: 2
scheduler_threads: 4
The main item I have tinkered with is the scheduler_threads. When I leave it at 2, the servers memory usage stays very low - we have 20Gb allocated towards the server, and when running the pregen with 2 threads, it goes from 2 to 4Gb of usage. When I change the scheduler_threads to 4, the pregen completely kills the server - it will eat all the remaining memory within 10 seconds of starting the pregen command. I have tried using the different jvm startup arguments, first, I tried the "high memory/core count" configuration; when that didnt work, i tried the low/mid memory count arguments and ran into the same problem.
