Hello All,

Over the last couple of weeks, I have been experiencing increasingly frequent crashes with VBox. I'm currently running vBox 5.1.4 on a Fedora 24 x86_64 host system with a 32-bit Windows 10 Pro guest, but I also experienced my problem before upgrading from VBox 5.1 to 5.1.4. At random times, I will do a simple action in a program running on the Windows guest, like click on a button, select a menu, etc., and the guest system will instantly disappear. The guest's window on the Linux desktop just snaps shut and the Virtualization Manager says that VM "aborted." This has happened three times today.

The hardware I'm using is a Dell Inspiron 15 Model 7548, Intel i7-5500U processor running at 2.4 Ghz, 12 gigabytes RAM with 4 gigabytes given to the guest and 256 megabytes video RAM for the guest. I took a look at the log for the VM, but, given my limited knowledge, I didn't learn much from it. I have attached a copy of the log leading up to my latest crash.

If anyone has some suggestions for how I might avoid this problem, I'd really be thankful!

A couple of things you can try:

• Try to disable Audio on the guest.
• Try one of the latest test builds (https://www.virtualbox.org/wiki/Testbuilds).
• Lower your guest CPUs to 1. Your host has 2 CPUs (cores). Don't give all of them to the guest.

Thanks for the suggestions! I'll give them a try.
