Hi all, hoping someone might be able to provide some guidance to resolve a recurring issue.
I have 3x RT-AX55 routers, 2 are setup as AiMesh nodes. All were purchased in April 2022. For the first 6-8 months we had no issues, everything was completely stable and I never needed to manually reboot the router due to connectivity issues. However, over the last few months I've noticed that about weekly everything starts loading really slow and some devices start significantly lagging with loading pages/apps, to the point that some devices aren't even able to complete DNS lookups. A reboot of the main router completely clears up any connectivity issues for about a week.
When this happens, if I log into the router and look at the logs I see it's filled with similar to the following 3 lines:
However the system status in the web UI shows I should still have free memory.
Which seems aligned with when I log into the router through SSH and run
Not sure if it's relevant, but if i check disk space using
I have AiProtection, Guest Wifi, Parental Controls, and QOS disabled (never been enabled). Firewall is enabled but DoS protection is disabled and there's no URL/Keyword/Network Service filters enabled and I haven't added any inbound firewall rules. Logged Packets type is set to none. This model doesn't have USB ports or a file server option I can disable, as far as I can tell. I'm using stock firmware, current version 3.0.0.4.386_50460-g5174ed0.
I've tried factory resetting on all units, manually reinstalling the firmware after downloading direct from Asus, and manually reconfiguring everything in hope that would make a difference, but it did not.
From this point, I'm not sure where to look or what my next step would be. Any help is greatly appreciated!

df -h it does show the root directly has no space.
