Anyone willing to explain?
I see there are warning about a unsigned int, is it referring to the storage saving in database or whats the problem?

[TFS 1.x+] How to NOT write LUA scripts or how to crash server by LUA script

There are many tutorials about writing scripts for TFS 1.x, so I decided to write short tutorial how to NOT write scripts for TFS 1.x. In this tutorial I will describe two common mistakes that result in server crash! First thing that everyone notice when they change engine from TFS 0.x to 1.x...
otland.net otland.net

C++: 
#4  0x00005555558263d0 in Player::getStorageValue(unsigned int, int&) const ()
#10 0x000055555579f182 in LuaEnvironment::executeTimerEvent(unsigned int) ()

Somewhere in your datapack, you have an addEvent calling getStorageValue without validating the object (player)

Only way is by walking through everything or is there a way finding out where it sits?

Most of the IDE's have the advanced search function and generally the shortcut is Ctrl+Shift+F
This includes Sublime Text & Notepad++

you can wrap this function:
Lua: 
function example(x)
print(x)
return x*2
end

local wrapped = example

function example(x)
print(debug.getinfo(1).source)
local output = wrapped(x)
return output
end

example(1)

You say if I put this in like global and add it onto every addevent i get more info if it crashes and runs in gdb?

@Mjmackan Nah, he suggest to wrap addEvent and print there debug info before it gets executed, like (not tested):
Lua: 
local oriAddEvent = addEvent

addEvent = function(...)
    print(debug.getinfo(2).source)
    return oriAddEvent(...)
end
