Cannot Load DDNSID/Dynamic Key Cert not found SYSLOG

[j.hartwell]

I have enabled SYSLOG on my S8POE and was flooded with Cannot load DDNSID and Dynamic Key Cert not found. I am just curious what this is?

A long shot…is there by any chance any correlation to CPU spikes for the S8 (WebUI network device stats pop-up and/or top through SSH)?

Thaaat would have been my question as well…

Seems like the majority of the entries are occuring at HH:MM:43, with some additional entries at :48 and :38.

Just curious if there is any relation to this:

High resource utilization

FWIW: I had another two S8 picked up and unboxed today and can confirm they also behave the same in terms of system load peaks. Edit: Nothing more on any latency or connection issues, BUT, I noticed that the peaks are very synced throughout all my now three switches and also the AP6 Pro. It occurs once every 60 s. See attached screenshots below. Screenshots of peaks at 60 s apart... There are also out of sync peaks in between those 60 s. And, the peak occurs for the AP6 Pro as well, although …

These CPU-spikes happened, for my system, consequently at Uptime HH:MM:43. So, if the uptime happens to be counted from a full minute it may be very much related (but may of course still be completely unrelated), and otherwise if the uptime is counted from the actual system start chances are drastically lower (1/60 chance). I haven’t checked uptime for those spikes over reboots
