hap ac2, exact same dns configuration. There must be something different on those devices showing this problem. Maybe it's a service or setting interacting with the dns, which is disabled on my devices.. just a guess.

Maybe, in my cases usage of CRL is disabled. I use a Cloudflare DoH servers

strange, I still see no increase in memory usage. The screenshot I posted is from a 750G r3 (hEX). Does this only occur on arm devices? We use this device at work to provide internet access to guests, not too much traffic, around 100GB/month. Not only ARMs devices, at RB951G-2HnD the same situation

Memory leak on my hap ac^2 after upgrade

When I just open and immediately close without saving the quick settings, the configuration on the device changes. hap ac^2
