Windows server 2008 R2 crashes

[wishmaster]

Hi, colleagues!

Guest server works in a bhyve as WSUS server and has 3 disks. One of this disk (not system) is used as backup disk for an application.
I have forgotten about this backup scheduler and disk sometimes become full. And I have figured out that when disk full, virtual machine crashes.

Command to run bhyve vm:

bhyve -c 3 -p 0:1 -p 1:2 -p 2:3 -s 0,hostbridge -s 3,ahci-hd,/dev/zvol/my_zroot/VM/img/win2008r2/disk0 -s 4,ahci-hd,/dev/zvol/my_zroot/VM/img/win2008r2/disk1 -s 5,ahci-hd,/dev/zvol/my_zroot/VM/img/win2008r2/disk2 -s 6:0,ahci,hd:/dev/zvol/my_zroot/VM/img/win2008r2/disk3 -s 10,virtio-net,tap0 -s 31,lpc -l bootrom,/VM/distro/BHYVE_UEFI.fd -m 6G -H -w windows1 &"
