Hello,

I’m currently experimenting with 1.10.0-rc1 and I encountered a strange issue. I’m launching julia with `JULIA_NUM_THREADS=auto` on 3 AMD computers in the lab. On two threadripper (32 and 24 cores) everything works fine and `Pkg.status()` returns quickly. On the third computer (AMD Epyc 128 cores), `Pkg.status()` hangs forever while `top` reports the process using around 12800% cpu. On this same machine, if I set `JULIA_NUM_THREADS=128`, `Pkg.status()` returns quickly. All 3 computers use the same installation through an NFS automount, the partition for the install is on a fourth machine.

The same tests with Julia 1.9.4 all run fine everywhere with `auto`. Any idea on how to further investigate (or solve) the issue? I would prefer continue using `auto` as I often launch my code on computers with various core counts.

Thanks in advance for any suggestion!

Are they all using the same Julia depot?

Yes, same depot. I’m using a different depot when running on Intel computers.
