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.
I'm using xrdp, so that might be why?
I deleted my ~/.arm, ~/developmentstudio-workspace and any eclipse-related directories I could see, and the memory leak appears to have stopped. I've been able to leave Development Studio running for over a day with no problems!
Ok, that's good news - thanks for letting us know :)
