A "major" linux app (for ubuntu-18-20) (uses Qt, QtOpenGL and Java, is multi-threaded) actually causes FreeBSD to reboot. No messages in /var/log why. The app runs as a normal user. The last version runs very well: but the GUI has compiled against "new versions of everything bad" (not that anyone could tell there was a reason - the app doesn't use any of the all new libs?)
I'm un-aware if "normal users" have authority to execute HALT on Intel platforms running freebsd which is basically my question (i hope not): So where in the kernel might execute halt in a panic rather than shutdown due to ... linux emulation missing support? Or should I heavily suspect a video driver fault not the kernel? That's really my only question. What in freeBSD would panic to HALT or if nVidia card can cause reboot? Or does Xorg have any "halt" instructions hidden somewhere if it flubs?
All I know is the screen goes dark very soon after the app begins to load and reboot happens 1 sec after (normal load is: a 5 sec disk read, then a 2D spash comes up showing progress loading another 5-10 sec). So I'm unsure I can blame GL but maybe. It's just plain strange to me I've never had an app running as a normal user reboot a unix like that before.
