Lua Small problem.

[Potar]

Hello i wrote a Global Save script, i have two problem's.

Everything works but if I have to worry about these errors?

First:

ots: /usr/include/boost/thread/pthread/condition_variable_fwd.hpp:38: boost::condition_variable::~condition_variable(): Assertion `!pthread_cond_destroy(&cond)' failed.

Second:

[5:49:00.673] [Error - GlobalEvent Interface] 
[5:49:00.673] In a timer event called from: 
[5:49:00.673] data/globalevents/scripts/global.lua:onTime
[5:49:00.673] Description: 
[5:49:00.673] (luaAddEvent) Callback parameter should be a function.

And there is my script:

function onTime()
return prepareShutdown(math.abs(math.ceil(10)))
end

function prepareShutdown(minutes)
	if(minutes <= 0) then
	addEvent(close(), 1*1000)
	addEvent(global(), 10*1000)
		return false
	end

	if(minutes == 1) then
		doBroadcastMessage("Server is going down in " .. minutes .. " minute, please log out now!")
	elseif(minutes <= 3) then
		doBroadcastMessage("Server is going down in " .. minutes .. " minutes, please log out.")
	else
		doBroadcastMessage("Server is going down in " .. minutes .. " minutes.")
	end

	shutdownEvent = addEvent(prepareShutdown, 60000, minutes - 1)
	return true
end


function close()
doSetGameState(GAMESTATE_CLOSED)
end

function global()
doSetGameState(GAMESTATE_SHUTDOWN)
end
