We have an x86_64 machine running Hydra and an aarch64 builder. On recent versions of Nix/Hydra (I've tried the one with Nix 2.25 pre-LegacySSHStore and Nix 2.26 post-LegacySSHStore), it looks like x86_64 jobs that depend on outputs built on the aarch64 machine (e.g. deployment scripts that use aarch64 system closures) are getting stuck indefinitely on "Sending inputs", and cannot even be cancelled.

Pure x86_64 and aarch64 jobs are still fine.

Has anyone had this too?

Nothing significant seems to be getting logged on either machine.
