After approx. 6 hours of processing, i get the following lua error :

The string "Internal error" appears nowhere in the source code of
LuaJIT. Also, a Lua stack overflow would show with a lower case
error message ("stack overflow").
I suggest you look for the component that generates the error.
Yes, sorry : "Internal error" is coming from our layer, and we get a "stack
overflow" from LuaJIT (ie in lower case).
You could try to lower the available stack size (I think that's
possible somewhere...) to avoid 6hour+ runtime for debugging. And a
traceback would certainly help to pinpoint the problem in no time ;)
Also, it could be that you don't do tail recursions correctly in some loop, like
function frame()
-- stuff
return frame()+1 --<- +1 prevents successful tail recursion
end
Beyond that, I think to remember that some debug options disable tail
recursions and therefore can also lead to stack overflows where none
should happen. But could be wrong on that.
