14136,VM(Windows 7) crash on Ubuntu,coRp,,"Hello,

My VirtualBox VM(Windows 7 Pro x64) start crashing. It is crashing on random intervals, usually within 2 hours. It does not matter if I work on VM or it's only on background. I'm not able to determine any reason why it's crashing.

I don't see any records in host's dmesg command.
Core dump attached.
VBox.log attached.

I'm running Virtual Box on Ubuntu 12.04.5 LTS - 64b. I have only 1 plug-in in VirtualBox: Oracle Virtual Box extensions(up to date).

This issue was here in version 4.6.26, then I upgraded to 4.6.28 and it's still there. Guest tools are up to date.

Thank you for any help.",defect,closed,VMM,VirtualBox 4.3.28,duplicate,"ubuntu, crash, windows7",,Windows,Linux
