Hello Marius,

I suspect this is caused by https://issues.guix.gnu.org/59510 which causes the worker threads to bail out. We can probably merge those two issues. The /var/log/cuirass-remote-server.log file on Berlin also indicates when the build-succeeded or build-failed message is received by the server, and how long the fetch from the worker took. Thanks, Mathieu
