OSX Hypervisor Kernel panic mp_rendezvous_action()

Kernel Panic: ​https://gist.github.com/anonymous/47239d64b01c7f5a8aef

This is a reproducible kernel panic.

Setup:

Hypervisor: OSX 10.10.3 12GB ECC RAM 2x Quad-Core i7 (16 cores total).

Virtual Box: 4.2.28 & 4.3.28 ( i haven't tried older versions yet ).

Guest: Ubuntu 15.04 RAM: 3078MB CPU: 8 cores VTX/Nested paging enabled

NFS share mounted in a Ubuntu 15.04 VM. Ubuntu 15.04 VM is running crash plan and backing up the NFS share. The Ubuntu 15.04 VM is a local vdi on the OSX Hypervisor. Running the backup causes the hypervisor machine to kernel panic (with the above panic trace) after a seemingly random amount of time (usually less than an hour).

I have several vm's with VDI's on the NFS share: CentOS 6/7, Ubuntu 12/14, Debian 6/7, all of these run without any issues and do not cause kernel panics. I have tried leaving these running and leaving them off to see if there was some conflict between the vms that was causing panics. Both ways still cause panics.

The only 3rd party kext's I have installed are the virtual box ones:

If there is any other information I can provide let me know.

Please provide a VBox.log file of such a VM session.
