Note the Unix.Unix_error(Unix.ENOMEM, "io_uring_register_buffers", "") error means that the CI worker decided not to let it lock enough memory. This often happens when the cluster is busy.

I see one of the tests wants to create a socket in /tmp, which fails because that's not mounted in CI. I'll change that upstream - does it need a new release?

The nnp test says:

  - downgrade ocaml-variants    4.13.1+options to 4.12.0+domains+effects

Is that expected?

Is that expected?

it’s not. I saw that some time ago (it’s only switching when it is not available, so it’s not a huge issue) but I was kind of hoping for ocaml/opam#5002 to be merged and backported a few weeks ago but obviously it wasn’t. I’ll try to hotfix opam-repo-ci but for now we can ignore them.

if you can, that’d be much appreciated. /tmp is not available in the sandbox, you need to use $TMPDIR whenever available

I think I might just disable the eio_main tests until we have the ENOMEM thing fixed. Otherwise, it'll generate lots of random failures in opam-health-check.

Thanks!
