i5 8500t to run 16 AI Surveillance tasks crashed

[vinnfts]

I'm running DVA 1622 on Promox with i5 8500t (pass-through iGPU). I tried to run 16 tasks of AI (8 Face Detection + 8 Deep Video Analytics). Sometime, the Face Detection tasks crashed or Deep Video tasks crashed. I have to run this bash few times to make it work again. Anybody know the reason why?

#!/bin/bash

# stop surveillance app
/usr/syno/bin/synopkg stop SurveillanceStation

# open surveillance database
/volume1/@appstore/SurveillanceStation/bin/sqlite3 /volume1/@appstore/SurveillanceStation/system.db <<'END_SQL'
.timeout 2000

# enable all face recognition task
UPDATE face_setting SET enable = 1;

# enable all deep stream task
UPDATE iva_setting SET enable = 1;
END_SQL
sleep 5

# start surveillance app
/usr/syno/bin/synopkg start SurveillanceStation
