10.2 Release - no core dump found after crash

Been trying to get a FreeBSD VM server running on Azure on a "Standard DS" size VM (so I have access to SSD storage for PostgreSQL).  The "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).

Here is the "last" log from the last two days:

There are boot times without previous shutdown times - and there is that "crash" text (which is why I'm thinking it is a crash).

I added this to /etc/rc.conf:


Here is the info on the swapfile:

sudo swapinfo -h
Device          512-blocks     Used    Avail Capacity
/dev/gpt/swapfs    2097152       0B     1.0G     0%

Server has 3.5 GB of RAM.

Here is the boot log after a crash (says there are no core dumps found... any way to figure out why it is not dumping the core?):
