VBOX session crashes - aborted - on NAT: DHCP offered IP address. Fixed in the past, reintroduced.

[Flamestring]

Hallo

Running Windows 7 guest, hosted in VBox 5.1.4 under Fedora 24. Same problem on RHEL6 and RHEL7.

Session of VM randomly crashes without notice, getting status ABORTED. No obvious errors in neither Windows not Linux logs. In VBox log, after every crash there is this single message as last one:

NAT: DHCP offered IP address 10.0.2.15

I've seen same problem beeing solved in much older version of VBox: https://www.virtualbox.org/ticket/13874

I guess the error got reintroduced along the VBox evolution.

Could you please check and fix according to previous solution?

Thanks a lot

VBox log for crash (aborted).

[Valery Ushakov]

That line is not necessarily related to the crash, it's just that during normal course of operation not that much is written to the VBox.log file, so this line just happens to be the last "interesting" event reported. As a quick check you can tail -f the log file to see if the crash happens immediately after that line is logged.

It's impossible to tell more without a core dump.

Do you have a core dump available?

I'm wondering if this perhaps the same thing I'm experiencing. It sounds very similar (#16120)

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, as has been requested.
