Same thing if I try to run oned manually:

# su -s /bin/bash oneadmin -
$ oned -f
$ echo $?
139

How to reproduce

• Download the last alpine-vrouter (KVM) image from marketplace
• Create new virtual router from it with name aaa
• Go to the Virtual Routers --> aaa --> Attach NIC
• Select your network, then click “Attach”.
