I’m running a CCR2004-16G-2S+ on RouterOS 7.18.2. After about 20 days of uptime, WAN performance degrades—upload/download become unstable, and only a router reboot temporarily fixes it.

Has anyone seen Queue Tree performance degrade after long uptimes? I have tried with and without fasttrack enabled, both scenarios fail.
Is there a way to “refresh”/reset QoS without a full reboot (scheduler script, connection flush)?
What should I monitor or clear?
