It sounds as if it's crashing for some reason. But first, check the
admin web GUI to see if you have inadvertently set it up to shut down or
restart at specific times.

If its crashing, it's probably telling you why -- but those messages are
going to the console which you can't see. What is the output from the
"free" command when it is running? Is there any correlation between
certain activities or load and the failure?

And don't forget to run a filesystem check on the drive(s).
