Virtualhere server crashing on Raspberry Pi 3B+

Good morning,

Just wondered if anyone had come across a solution for what appears to be a server process crash on Raspberry Pi 3B+

Everything installed and running brilliantly - I'm using this to host a Steinberg USB dongle so I dont have to cart the device around to use Cubase 10.5 Pro. Its quick, easy and it works!

But I noticed that the server has stopped after a few hours . It's an easy fix to restart but it would be great to have to not do this if possible. Here's the process state after crash, and after restart:

pi@raspberrypi:~ $ ps -ef | grep vh
pi 11324 7425 0 10:43 pts/1 00:00:00 grep --color=auto vh

pi@raspberrypi:~ $ sudo /home/pi/Downloads/vhusbdarm -b

pi@raspberrypi:~ $ ps -ef | grep vh
root 11591 1 5 10:43 ? 00:00:00 /home/pi/Downloads/vhusbdarm -b
pi 11755 7425 0 10:43 pts/1 00:00:00 grep --color=auto vh

When I check the logs I see:

pi@raspberrypi:~ $ cat /var/log/syslog | grep vh

Anybody got a fix for this? Any help very greatly appreciated,
