afaik the mainline limit is 4096 threads. HP sells server with 32 sockets x 60 cores/socket x 2 threads/core = 3840 threads, so we are pretty close to that limit.

I had no idea we had socket counts so high, do you know where I could find a picture of one?

		It's bit cheating because it's cluster based system: https://www.hpe.com/psnow/doc/a50004268enw So 4 sockets per chassis, up to 8 chassis in a complete system. Afaik OS sees it as single huge system, that is kinda their special sauce here.

		Sounds like a HPE Compute Scale-up Server 3200, but again keep in mind that's something where there's probably a fabric between nodes one way or another.
