Friend's server crashing on startup with nothing logged

Not my server, but my friend's, though I do have access to it.

The server is crashing shortly after reaching the end of the queue. Nothing new appears in the log at all, error or otherwise; when I go to the logs page, it shows the logs from when the server was up last night.

Here's the logs, which are from last night:

Nvm, just noticed there's a confirm button you have to hit.
