AppVM unexpectedly shut down and I don't know the exact reason

I currently use syncthing and veracrypt in same AppVM,

When I try to sync folders in veracrypt-mounted external HDD, the AppVM unexpectedly harts, and I don’t know exact reason why.

I guess there are reasons:

  1. lack of memory.
  2. Veracrypt bugs.
    2-1. When system try to access a damaged portion of the volume(if volume is somewhere damaged), then it could halt, but it’s mysterious why the VM itself shuts down?
  3. other reasons…

I think the second issue is the most suspicious, because file copy/move without syncthing also makes the same issue. But I’m not sure because just viewing the file in the mounted disk doesn’t cause the halting.

In addition, using a veracrypt with same external disk in windows qubes doesn’t cause the sudden stop without any warning.

I feel uncomfortable about this because the encrypted external HDD may be damaged by this force stop.

Could someone help me? Any ideas? Furthermore, are there a way to analyze the exact reason why AppVM is suddenly turned off?

I’m going to check logfile tonight. For that, How to save logs

Here is the log file :

You can access logs in dom0, look in /var/log/xen/console/guest-$NAME.log [1].

Mass file transfers between devices can abruptly shut down AppVMs, so transfer less each session as a workaround.
