I am using Virtualization Station 3.1.1125 on a QNAP TS-453U, FW 4.3.6.0993.
I have three VMs.
VM "A" is used as a Gateway using the Software "IPFire" (3 interfaces to 3 virtual switches: WAN, LAN, DMZ).
VM "B" is used for internal services and only connected to LAN (gentoo Linux)
VM "C" is used for external services and connected to DMZ (gentoo Linux)
The setup has been running fine for about two years.
Now today was the third time in a few weeks where I found VM "C" being down (switched off in the Virtualization Station). In the log files inside my VM I cannot see it having shut down or so. There is just a cut off in the middle of some process shortly before midnight and then I can see the bootup messages when I manually started it again.
Also in the QNAP Virtualization Station Log I can see a message "VM started" but I cannot find where it has been stopped. It just seems to have crashed or so on a Virtualization Station level.
The other two VMs are still running fine.
Is there a way to find out what happened? Some finer-granular log files where I can see what happened when the VM stopped running?
I am not sure if this is relevant but maybe as an additional Information:
I had a weird crash of VM "C" by end of May 2019. Obviously one of the older snapshot files of the VM's virtual disk was corrupted and so the entire file system was corrupted. The backup which I had created using Virtualization Station had the same problem. I was able to fix this using multiple older backups by selecting some working snapshot files out of each backup, so I could mount the virtual disk with a new VM and restore my files.
As I considered it unsafe to keep using this repaired virtual disk, I recreated an entirely new VM for VM "C" and created a new virtual hard disk with it. I then copied the system's files to the new virtual disk inside the VM just to be sure.
This was the point of time when the VM started to crash from time to time.
Thanks in advance for any hints.

edit:
I found a log file from QVM using the QNAP's ssh console. On 2019-06-12 I reinstalled the VM and rescued the data. The Events on 2019-06-21, 2019-07-09 and 2019-07-17 are the unjustified shutdowns I am talking About. As it is visible in the log files it always happens around the same time.
On 2019-07-17 between 21:10 and 21:25 I updated the NAS Firmware, so the VMs were suspended and resumed there. The one at 2019-07-17 21:53 is another crash.
My other VMs which are working only show the shutdowns due to Firmware updates and absolutely no events at the points of time when the VM "C" crashed.
One Thing I just noticed is that the working VMs are running in CPU mode "Passthrough" and the one which is frequently restarting emulates a Core i7 Nehalem. I will now also set this one to Passthrough and see if it will be stable again then.
Unfortunately I can attach neither a .log file nor a .txt file, so I put it as a citation here:
