High RAM utilization on RT6600ax

I was told by Synology a few weeks ago "I have inspected the Debug Log from ticket #xxx and have found that there is corruption in the Router's configuration. The corruption is causing packet loss on Wi-Fi networks, and causing an over-utilization of RAM." I was asked to perform a hard-reset (and no restore from backup) and then was told
"/proc/meminfo is showing high Memory utilization, and that the Router is using a small amount of Swap RAM, which may cause the Router to run a bit slower than expected.".
They then suggested I then do a factory reset i.e. " Router and open Control Panel>System, and expand the "Configuration Backup and Restore" button."

What is everyone seeing their configuration and memory utilization? Im only running Safe Access and here's my output from meminfo and top below. Is there a known patch for this or what could be happening here? Doing a hard-reset I would think is stronger than a factory-reset but not sure if I have to do this ALL over again! My system appears to be running fine but what is the norm for memory/RAM utilization on the RT6600ax? Loadavg is low but I do see that MemFree is 824Mb and free is only 82Mb BUT 223Mb cached. So what should this look like really? If I start adding packages e.g. threat prevention for example am I basically tapped out and unstable?

Realize not 6600, but for reference, I have examined CPU & RAM from DS Router, and on multiple 2600’s TP & SA NO VPN ITS ALWAYS BEEN ABOUT THE SAME. For years. Just checked 35-49 CPU 52 RAM
 
My RT6600ax, which is running SA, TP, VPN+, and DNS.
