No, they are still updated, it's just that your stats requests are sent to the new process, which still doesn't have new connections. There is no real "fix", if you have long sessions and you reload frequently, you end up with multiple processes each having their own sessions and own stats. With the new master-worker features in 1.9 you'll be able to check the stats of older processes as well (via the CLI) in case you really need this. Another option could be to figure why you need to reload often, which seems a bit contradictory with the need for long sessions. Maybe some operations don't require a reload. Willy
