ReleaseEngineering/How To/Handle an Idle Slave

• check SlaveHealth dashboard for idle machines
  • https://secure.pub.build.mozilla.org/builddata/reports/slave_health/index.html
  • any machine that hasn't taken a job for a time period > 5 hours is considered "idle" and the row color for the corresponding machine will turn orange.
• check buildbot.tac to ensure the slave is enabled and see which master it's on.
• tail twistd.log to see if the slave is really idle. In most cases, the slave has been idle since it started up. Note any differences.
• Reboot. Don't use `buildbot restart`, since it won't work on macs!
