When the cpu utilization spikes between 80% - 85%, it does cause issues with connectivity / latency. But after it subsides, it returns back to normal and devices are stable. This typically happens every 30 - 40 seconds, and always seems to be the RCSTATS task that matches the spikes.
The web and app dashboards typically show the similar spikes as the CLI / SSH session. The above screenshot still shows similar stats / tasks, and I have not made any additional changes to my network at this point outside of updated firmware.
Between the Alta Labs forum as well as the Alta Labs subreddit, I have seen a few posts about similar situations but it doesn’t seem to be a wide-spread issue. I initially posted on another forum thread and since was closed / split into a new topic on the 24th of January. The prior post didn’t yield any additional detail(s) / fixes / suggestions / changes, etc.

I was trying to find the additional posts I found prior, but am unable to locate them.
