I've set up a second z4 in as many weeks now, and both seem to have odd behavior.

The z4w would not update firmware from 14.1.2 to 14.2.2 and had high memory usage (14% available). I had to start a ticket which was addressed pretty quickly to have them force quit a pending update so that it would update again. It was odd as I had literally just unboxed it.

Set up a z4 today and it has the same problem, only this one also has a lot of JSON errors popping up when trying to install apps or sometimes when applying settings. I am still waiting on this ticket to get answered.

Is this common? Did I get a batch of lemons?

Im a bit concerned as I have a z6 install later today and really dont want to go through this a third time.
