I'm having some strange issues affecting many, though not all APs. Groups of SMs get an authen-reset and the re-reg together. Some APs get one or two of these events a day, some get dozens and the same SMs are not always grouped together, though the re-regs usually happen in groups of 2 - 4.
Signals and SNR are good and there is no obvious time patern.
Barry, are you using GPS Sync on all these, and if so are all co-located unis using the same sync source? I've been seeing this sort of thing lately, and it seems to show up only at sites where there is a mix of sync sources, or a site which is close enough to allow interference with a site running on either a mix of sync sources, or a different kind of source than the other tower.
I'd be curious to know if your sync situation was similar or different...
We are seeing this issue cropping up on our sites that are pulling sync via power port, all base stations are tied to a cmm4 sync source. Do you have a ticket or reference number with Cambium we can update our ticket with? Started noticing this on 15.1.5, but has degraded further on 15.2. Been trying to isolate the cause for a few weeks and luckily came across this post.
