Thanks for the reply. Yes, I've tried the old "turn it off and on again" a couple of times without result. I'll dig in a bit more to see if something has started hogging RAM recently.

Good to hear that they are still within the figures given on the system requirements page and it isn't a change in the project that would make this device unusable on the project going forward.

Thank you both for the tips. I was able to stop quite a few processes that were lingering after app updates and this reduced memory use to the point that the errors ceased.
