It's been continuously orange for a while... but the other box seems ok. We should try restarting it. Also, there should be two others, but qm-plinux-trunk-05 is missing.
qm-plinux-trunk05 is up and connected to the master, it is probably just starved of builds. If a machine hasn't 'won' a build in 12 hours it falls off the waterfall.
Still cycling orange. Found a permissions mistake in the configuration of the buildbot slave ("22" vs "022"). Fixed and rebooted the box.
Looks good now, cycling green.
