MY SERVER CRASHES EVERYTIME

[ParaklataChotou]

I DON'T KNOW WHAT'S HAPPENING.
"/home/stefan/mt-build/build/minetest_64/minetest/src/server.cpp" - Why it appears on my debug info? What's happening?

here's the 'error':

How can I stop this?

[ParaklataChotou]

Ok, I've tried to fixing changing the env_meta file. and by the moment is working. But it's very weird that there appears a UNIX directory, on my debug file. I want to know how can I protect my server against these 'hackers' or whatever.

I am guessing that is debug info from the person who built the Minetest package you downloaded (looks like sfan). The game displays that information so it is easy to see which source code file the error occurred in, and since sfan compiled it, the debug info remembers his paths.

How can I fix this problem? My world map is broken in some areas. When I go those areas, the game crashes. :\. Here is another error:

I just backed up the server. and that's it. It's fixed n_n. Thank you anyways. Now the error is not occurring. Sadly, I've lost part of a progress of my new spawn, but anyways.

How to backup your world? go to /minetest/world" folder, select one of those folders who says some kind of ip - if it's the ip of your server, then select it. Copy the map.mysql file, and paste it over the world folder. And that's it.
