This most likely is miner binary crashing. It crashes every few days, on every machine. You can resolve this by looping it in bash script, I posted it in this thread a few pages ago. Unless this is already fixed for Full units? I don't know.
Interesting, so you have the issue even if you're not using the stock Apollo software, but custom Linux OS and connect the miner to 'itself' using a short USB cable (that was you right)?
Yes, that's was mine idea, unfortunately miner binary (proprietary) crashes on everything. I looped it, so it works for me. Worst is for full package users, when it crashes, they have to kill entire machine including Bitcoin Node, so it can reboot and start over (unless this is fixed, I am speculating here, not using full package software kit).
Alright, interesting. Yeah I plan on doing your setup as well anyway; so it will be easy to put a bash loop around the miner execution

wihle 1; do ./miner; done
Received Apollo BTC Batch 3 Production Update e-mail just now.
Oh nice, I have not yet. Time really flew from August till now. Back then it seemed like it would take forever for Apollo to arrive, now it's coming in a month-ish..? Sick!
