It is not an error there. It says system shutting down.

Perhaps figure out why it SHUTS DOWN.

This isn't oops, error, POOF. This is the system intentionally shutting down.

It won't shutdown on its own because of load. Something is rebooting it for you.

I would start turning off services one by one until problem is resolved. The last one you turn off before it stops is the one the causes it. Then investigate why, turn on verbose/debuggin messages or run in in foreground to see what's up.
