reason is that switches in our factory are quite long without any updates
Answer this question: Is the factory willing to accept a 6-minute outage every, say, 6 months/
My fleet of 3850 runs on 3.6.X/3.7.X and 16.X.X. All our switches (functioning as a layer 2 switch) that are on 16.X.X need to be rebooted every 4 to 6 months because of memory leaks (see pictures below). All our switches on 3.6.X/3.7.X have an uptime of >5 years without any issues.
Picture above shows a memory utilization graph (control-plane) for the last 800 days. The switch (standone) is on 16.6.5 with an uptime of >3 years. This switch is on a standard "static" port, i. e. no Dot1X, and there is only one (1) wired client.
