Some questions about Instance settings

[eliptx]

Is there someone can tell me what's the meaning of "Minmum count of tasks before instance reboot"&"Number of completed tasks until forced instance reboot"?

Sometimes we need restart instances (browser windows) more often to free up used memory.
Minmum count of tasks before instance reboot means count of instance executions of projects by this instance after which the instance is restarted to free up used memory and other resources.
Number of completed tasks until forced instance reboot means number of successfully executed tasks before instance will be restarted.
