But note: having launched the loading of all races doesn't make the new archive candidate present all content in the proper form yet. Many background processes will keep running for several more hours, computing maneuvers and from them updating wind estimations. You should let the process finish before running the mandatory archive server content comparison. One way to track these background processes is by looking at the EC2 console's instance monitoring and there the CPU Utilization chart. You will clearly see when the CPU utilization drops from 100% to 0% when the background processes are done. Instead, you may choose to ssh into the instance and run a ``top`` command or similar and track CPU load. Alternatively, track the ``/home/sailing/servers/server/logs/sailing0.log.0`` file on the new archive server candidate. It will contain lines of the sort

that will keep repeating. Watch out for the ``queued tasks`` count. It should be decreasing, and when done it should go down to 0 eventually, although you may not see a log entry with "queued tasks = 0" necessarily.
