When you install the agent on new devices do you use the LB for the bootstrap beacon or specify a specific beacon? If you are going through the LB then it doesn't matter if it is a new install or old install, you need to have sticky sessions enabled. When the agent requests policy it gets a file that points to multiple files that need to be downloaded for the entire policy task to complete successfully. All of the requests for that single policy run need to go to the same beacon to ensure that the file being downloaded matches what was set in the initial npl download.
