Problem with the game

[SodixGamer]

Hi, I would like to know what is happening with minetest on my computer, because for some strange reason it tells me that there is an error
Something like this:

2018-07-12 03:35:47 ERROR[Server]: DEBUG STACK FOR THREAD b:
2018-07-12 03:35:47 ERROR[Server]: #0
2018-07-12 03:35:47 ERROR[Server]: DEBUG STACK FOR THREAD c:

2018-07-12 03:35:47 ERROR[Server]: DEBUG STACK FOR THREAD d:
2018-07-12 03:35:47 ERROR[Server]: #0

Please help me, I need to know :(

Minetest is a game engine, not a game

You need to show the actual error. Please post the last 40 lines of debug.txt

is this correct?:

The error is:

server.cpp:73: run: A fatal error occured: Failed to save block: disk I/O error

Do you have enough free disk space?
Is the file writable to your current user?

[SodixGamer]

I think the problem is in the disk space, because if it can be modified by the current user
The problem of space may be because I'm on a laptop?

[Krock]

It's only a problem when there's only little free disk space left. Check your drive information and let Windows (obviously using a Win64 build) calculate the occupied space if there's an option for it.
Also try adding an exception in your Antivirus for the "map.sqlite" file. Their disk I/O scanner may conflict with the database management.
