Memory leak in Arm DS 2022.1 (regression from 2022.0)

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.

  • Thank you for reporting this.

    Could I ask what target you are debugging? Is it a Virtual Platform (such as the supplied FVPs) or real hardware.
    If the latter, what debug hardware (eg DSTREAM-ST) are you using? Is it over USB or Ethernet?
