Hello Ludo,

Thanks for gathering those information.

Yes this is because a new remote-server is running on Berlin and it
sends an empty sequence at every connection:
https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/commit/?id=fc1641381d2a8a0472a71ef5ad2b64361faaaab4

All remote-workers must update, and I have deployed Cuirass
1.1.0-13.1341725 on all hydra workers + guix9p.

I have been trying to deploy that to overdrive1 for two days but Berlin
offloads the builds to kreuzberg which has some issues because a lot of
builds are timeouting:

Right, this is problematic. I can't remember why I chose to fork.

In the meantime, this should be fixed by updating to 1.1.0-13.1341725 so
we can close this one I guess.
