Ooooooooooooooookie-dokie, so I had an old save from right before things went to hell (pun intended?). I managed to narrow things down to it occurring when multiple monsters are on the same spot and one or more die, which I was able to reliably replicate starting from my save pre-overflow and spawning multiple arachnotrons/mancubus'. My mod 'som_zurvival,pk3' was responsible for the monsters being able to stack, but it was a combination of that and the upgrades I had that caused the overflow, as I attempted to replicate the issue with a clean slate and everything operated as expected. Other than the monster stacking caused by Zurvival, I don't think any of the other mods contributed to the issue, but if you need more info on anything, let me know.
I had the following mods enabled during this play through:
