VirtualBox 5.1.8r111374 aborts Debian guest after random period - NAT?

[sam.4325224]

I have a Debian Jessie guest running on a Arch host. After a seemingly random period of time, the guest will transition to the "aborted" state. I am yet to observe it happening, I normally notice after I find my VirtualBox guest has disappeared after a few hours.

I think it's possible that this is associated with an older ticket. Sorry if I have not formatted this ticket correctly, this is my first time doing so.

I will provide any information you require, please ask.

There is a number of audio regressions in 5.1. Please, can you disable audio in the VM completely and see if the problem persists?

If it does, please, provide a core dump.

Still relevant with VBox 5.1.10?
