Yeah, I would think this is a combination of triggers. I got it on another camera now, almost non-stop:

I disabled substream completely - played with resolution, bitrate, vbr/cbr, and none of it stops the errors. I do have pre-trigger enabled, with a value of 2 seconds. I really do want the pre-trigger, so I didn't try it disabled. I will now, but if that does solve the issue, that's not a very practical workaround. I sent an email to Ken again just a few min ago.
