I started the Monitor this morning and found that all of my running slaves were colored orange. If I’m correct, this normally means there is a license error. So I restarted the license server which usually fixes this. It did not. None of the slaves are complaining about licenses and they are picking up jobs. But they remain colored orange.
orange slaves means you have < 10 days left on your license file. Many a time this has saved a nasty situation
