@User this is looking much more stable now with a swap file enabled. Azure linux VMs are seemingly not provisioned with swap files as default. Something seems to have changed between 0.93 and 0.9.4 but perhaps this has only flagged up an issue for me with my system, rather than with Netmaker. Maybe it's just how low end this VM is that a anything lightly more demanding had tipped it over the edge. I really hope I haven't caused you to waste too much time on this if it's only me!
