Server crash - unknown cause

[Krock]

Hello,

Today (4 hours ago) I started a small server.
About 8 crashes and alot joins later I still couldn't find the source of these crashes.

What console/debug.txt sais:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

How do I debug those things?

EDIT: all recent crashes seem to cras because someone takes damage

[Krock]

Okay, the crash was caused by the bones mod, where I added this:

minetest.chat_send_player(player_name..", You died at...")

There.
