For what it's worth, I run hundreds of 24/7 unattended systems with the BBB. We have tested reboots into the tens of thousands, and with some work we are able to achieve zero failures.
Off the top of my head here are the key platform specific things I do that you might want to look at: 1) Mod the h/w to avoid the Ethernet issue (from another post) (this may be fixed in the latest kernel, but we locked the s/w down a while back. 2) Use a custom u-boot to avoid the uart boot issue. 3) Configure the file system as read only (perform all app-level read/writes on a separate partition). 4) Disable all journaling/logging, etc, except to temporary ramfs. 4) Force fsck to run and auto-recover on each boot (this was prior to running read-only, may not be necessary now). 5) Remove all unneeded processes. 6) Enable the watchdog. 7) Use 'allow-hotplug' on the ethernet connection. 8) There was an issue with USB mounting causing the CAN bus to fail, but this was resolved with a patch to the kernel I submitted a year or so ago. Prior to the fix I had a script checking for a failure and re-init'ing as necesary. Have you been able to ascertain how the boot sequence fails, e.g. run 30k reboots and record serial output? Cheers, Andrew.
