VirtualHere client crash on macOS 12.1

Hi Michael,

Thank you for adding Support for MacOS Monterey. Sometimes, I am seeing VirtualHere client crash ( Abort trap: 6) when using USB serial device like Arduino Due, Prolific USB to Serial adapter with VirtualHere client 5.3.4 (installed as service) on macOS 12.1.

$ sudo launchctl list | grep com.virtualhere.vhclient
- -6 com.virtualhere.vhclient

$ sudo launchctl print system/com.virtualhere.vhclient
system/com.virtualhere.vhclient = {
active count = 0
path = /Library/LaunchDaemons/com.virtualhere.vhclient.plist
state = not running

program = /Applications/VirtualHereUniversal.app/Contents/MacOS/VirtualHereUniversal
arguments = {
/Applications/VirtualHereUniversal.app/Contents/MacOS/VirtualHereUniversal
--log=OSEventLog
-n
}

default environment = {
PATH => /usr/bin:/bin:/usr/sbin:/sbin
}

environment = {
XPC_SERVICE_NAME => com.virtualhere.vhclient
}

domain = system
minimum runtime = 10
exit timeout = 5
runs = 1
successive crashes = 1
last terminating signal = Abort trap: 6

spawn type = daemon (3)
jetsam priority = 4
jetsam memory limit (active) = (unlimited)
jetsam memory limit (inactive) = (unlimited)
jetsamproperties category = daemon
jetsam thread limit = 32
cpumon = default

properties = runatload | inferred program | system service
}

I saved the Crash Report for VirtualHereUniversal. Let me know if this would be helpful and if you want me to email or post the Diagnostics Report.

Also, I have a few questions regarding the OSX client,

1. I am not able to see any kernel messages in console related to “hcd”. Can you please point me to where I can find VirtualHere client messages related to USB connection on macOS (Similar to "vhci_hcd" in syslog on Linux ).

2. Sometimes after the crash, "com.virtualhere.vhclient" service won't start again even after the reboot. Is there any reason why this could happen?

Thanks,
Arun
