There seems to be two problems the memory warnings, as well as the signal 9 : killed error

For mostly every single object and listener i canceled them out but
object:removeSelf()
as well as
object = nil

i tried to make the functions local but on some functions it didnt work when it was local. There are many functions in my project would this be the problem?

On every level i also put collectgarbage( “collect” ) and it still has the same effect
