Been noticing a few issues with cnMaestro while deploying firmware 15.1.3. Every now and then cnMaestro seems to get stuck on the last SM getting updated at "Downloading the firmware image". Sometimes it helps rebooting the SM and othertimes not. For instance , it's been stuck for about three hours trying to update a SM unit that's clearly offline. I even tried rebooting the cnMaestro server out of desperation since there doesn't seem to be any other way of killing the update job but with zero success..
I'm running version 1.6.1-r10. I don't think I had simmular issues on previous updates with the previous version of cnMaestro. So it might be something that got introduced with either the new firmware (15.1.3) or the new version of cnMaestro.
