I have CSA on 2900 plus machines I have a handful of machines (around 50) that will not take the scheduled update. When you click on the host through the MC and get its info it will tell you that the host has a scheduled update but it acts like it is hung up right there. I have these trouble machines update scheduled 24/7 to make sure get the update. I tried rebooting, making it poll manually, and reseting it through the MC. Is there something I'm missing? Why did it work on the other 2,850?
