Something is crashing the map-server, run your server with gdb and once it crashes upload the output here. https://github.com/rathena/rathena/wiki/GDB

The error you received, "Server received crash signal! Attempting to save all online characters!", is a generic error that means absolutely nothing besides "your server crashed". You will always get this same error. You most likely have two unrelated crashes there.

As cook1e said above, you want to run your server with gdb (there is a link provided in his post that explains how to use it). Gdb is a debugging tool that will give you a stack trace. You will get the crash reason, followed by the line in your source code that crashed the server, followed by the functions that called your code step by step. To print the stack trace, you will want to use "bt full" after the crash.

You should also always run your server with gdb as you can't predict when a crash will happen.

Once you have the stack trace, you can share it here and people can tell you how to fix your code. Or they'll ask you to provide the code surrouding the crash. Or, if the error is obvious, you might be able to fix it yourself. But either way, we can't help you without a gdb stack trace. Goodluck!

When i logged in VNC, i've seen something which likes @reloadmobdb..continued with

[Error]: Server received crash signal! Attempting to save all online characters! Segmentation fault

thing is no 1 is there to do @reloadmobdb then how it was doing auto reloadmob db? so i replaced old mob db txt from back up n recompiled n restarted server and did @reloadmobdb no crash happend. My server uses 2 mob db 1 ) is mob_db.yml & 2) is mob_db.txt during test never seen those issues but frequently this started happening...

Probably outdated rAthena? mob_db was converted to YAML fairly recently (16 Feb 2021).
