I've noticed that Arm Development Studio 2022.1 seems to have a fairly major memory leak, at least when running on Ubuntu 22.04.1 LTS.
When I launch it and just have an editor open, scrolling around and moving the cursor causes resident memory usage to keep going up - in one test I watched it go up to over 20 GB.
If I attach to a target and start debugging, I have maybe 5 minutes before all 128 GB memory is used up and the OOM reaper kills it.
I've just tested going back to Development Studio 2022.0 and it's much better: resident memory usage is around 3.5 GB, even when debugging an attached target.
To expand on this, I’m not using the N2 target that’s built in: I instead created a new model configuration database and imported the configuration from a running instance of the FVP.
