Looking into the first test failure:

=================================== FAILURES ===================================
________________________ test_public_modules_importable ________________________
scipy/_lib/tests/test_import_cycles.py:18: in test_public_modules_importable
    assert pid.wait() == 0, f'Failed to import {PUBLIC_MODULES[i]}'
E   AssertionError: Failed to import scipy.cluster
E   assert 1 == 0
E    +  where 1 = wait()
E    +    where wait = <Popen: returncode: 1 args: ['/cvmfs/dev.eessi.io/riscv/versions/2025.06-001...>.wait
        i          = 0
        pid        = <Popen: returncode: 1 args: ['/cvmfs/dev.eessi.io/riscv/versions/2025.06-001...>
        pids       = [<Popen: returncode: 1 args: ['/cvmfs/dev.eessi.io/riscv/versions/2025.06-001...>, <Popen: returncode: None args: ['/c....io/riscv/versions/2025.06-...>, <Popen: returncode: None args: ['/cvmfs/dev.eessi.io/riscv/versions/2025.06-...>, ...]

Looks similar to the ones reported in scipy/scipy#24163. There is no mention, however, to: OSError: [Errno 24] Too many open files.
Also, there the Popen only appears once while we have the Popen message 4 times... it looks like crucial to somehow run the tests sequentially with just 1 thread.

Hi, SciPy maintainer here. I happened to notice this and opened scipy/scipy#24537 to address it. If there are more such issues, opening issues or PRs to address those is very welcome. It's normal for us to have to patch the test suite to support usage on platforms that we don't (yet) exercise in our own CI.

Great! Thank you very much, @rgommers .
