For anything DAZ, I'd certainly recommend DAZ Decimator. It's a bit expensive, but well worth it.
Not only it's fast and stable, but the main advantage is preserved morphs.
CC LOD would wipe out hair tweaking morphs (that is if you transferred them with hair).
The thing is, the LOD tool was working fine till very recently on the exact same task (1 million+ count). I had actually reduced the count considerably already but wanted to have another pass at it from scratch and now it just hangs.
I have raised a ticket with support on this.
PreLOD reduction

PostLOD reduction
