Can you check the uptime displayed in the system status? My guess is that userspace crashed, but the kernel didn't -- in that scenario, init will try to restart userland, so you'd see the boot animation come up again.
You are correct, 78 hours uptime immediately after last SOD/init reboot of userland (whatever this should be called).
Jumping to conclusions, part 2: both issues are caused by the UsbDebuggingManager file descriptor/memory leak with beta 2 -- if you're building yourself, or know how to edit /init.encore.rc in the initramfs (ramdisk), apply
https://github.com/NookieDevs/andro...mmit/b93d7551841d235ac1fa50ae2d315afb39879005 and that problem will go away. I believe that disabling USB debugging in settings and rebooting will also stop that from happening.)
Have not had much time available, disabling USB debugging seems to have helped some (not happening as frequently), but has not completely solved the problem. Will try edits to init.encore.rc when I get time.
