nDAX "Killed"

So I'm running nDAX on a raspberri pi. Sir, you are a godsend for creating..thank you.

I am having an issue however. Randomly nDAX quits in terminal and says "killed". Then I restart it and it has an error, then starts working again. I can't reproduce it, but is usually after an hour or so of it running. Is it an idle time out or something possibly?
