I guess this is one of the slaves that was brought from production to staging and it has never connected to staging-stage http://staging-master.build.mozilla.org:8010/builders/Linux%20mozilla-central%20nightly/builds/209/steps/shell_11/logs/stdio
I have sshed to staging-stage from that machine and hopefully it fixes the problem
Are you using rsync or scp to upload the files? In either case, you could pass an option similar to "ssh -o 'StrictHostKeyChecking no'" to make ssh ignore fingerprints, if you don't care about security for a staging instance.
