hiya,
how much RAM does the VM have?
Yes, you need to either run dumpon or reboot once you update /etc/rc.conf .

"Standard DS" series of VMs also have faster/newer CPUs than the
original "Standard A" series of VMs. I am using the image of FreeBSD
from here: https://vmdepot.msopentech.com/Vhd/Show?vhdId=56718&version=61117
. After setting up the VM it started rebooting every hour or so. Initially I
thought this was an Azure issue and Azure was forcibly rebooting the VM because
it wasn't getting health reports back. But I don't' believe this is
the case anymore and I think FreeBSD is crashing. (Note: I have setup a FreeBSD
VM with a "Standard A" series VM and that seems to be running fine -
though it looks like it might have crashed after about 38 hours which is much
better than crashing after 1 hour).

Hm, the runtime going backwards is a bit odd, maybe they fixed that in -HEAD recently. Other than that, yeah, you'll need a crash dump or at least some screenshot when it does reboot. -a
