I have 32 GB of memory as well and even with 17 of it free, it fails to allocate. Makes me wonder if some calculation is just going haywire and overallocating as a singular massive blob! Sorry I can't help triage it further, I'm just not sure what tools I have to figure out exactly what allocation is failing!
EDIT: ran it from a fresh boot, with a full 29.8 GB of memory having never been touched, and it still hit OOM. So something's asking for an absurd amount of memory up front!
