I'm using VirtualBox (Version 5.1.38_Ubuntu r122592) under lubuntu (Linux hostname 4.4.0-148-generic #174-Ubuntu SMP Tue May 7 12:20:14 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux) to start turbo debug under a DOS 6.22 VM.

When I start td.exe VirtualBox hangs and completely locks my desktop.

Here the screenshot:

Do you know how to solve this issue? What's the reason?

Thanks in advance.

  • This looks like an error in VirtualBox. You should follow the instructions provided in the window you have shown in a screenshot. – Melebius Jun 5 '19 at 9:05
  • @Melebius. I hope someone knows the problem and help me to solve it ... :) – Sir Jo Black Jun 5 '19 at 9:10
  • That’s OK but I’d expect it to be much more probable on forums.virtualbox.org than here. And you should provide all the information requested in the window. – Melebius Jun 5 '19 at 9:14

The most plausible explanation is that VirtualBox (froze your Ubuntu because it) used up all the available RAM. Maybe test it while keeping an eye on top?
