memory leak and BHleak showing a nil class replicating on certain conditions: how to track it down?

pie

Hi, I am using "BHleaky" - source and info in this post -
http://giderosmobile.com/forum/discussion/2645/help-with-memory-leak/p1

I got this error:

leaky.lua:44: bad argument #2 to 'format' (string expected, got nil) stack traceback: leaky.lua:44: in function 'printAllInstances'

I made a slight mod to avoid it, so that it can work, and it works (to a certain extent):

function EventDispatcher.printAllInstances(tag) print("*** OBJECT SNAPSHOT", tag or os.date("%c"), "***") for class, tally in pairs(EventDispatcher._allObjectsBag.contents) do local classname = getClassName(class) -- ADDED if classname == nil then classname = "unknown, class nil" end -- ADDED print(string.format("%s has %d instances", classname, tally)) --UPDATED end print("*** OBJECT SNAPSHOT END ****") end

My problem is that this "unknown class" it's there from the beginning of my level loading, and on certain conditions it (they) become more and more unknown classes, each always referenced by 1 instance.

I'd like to understand which one it is, and if its moltiplication is given by the impossibility to remove it from the list, since its class.name is nil..

I'm trying to print out everything is being added if self.class is nil, but my output becomes mostly unreadable, because there are a lot of userdata being processed.

function EventDispatcher:postInit() EventDispatcher._allObjectsBag:add(self.class) --ADDED if self.class == nil then for i,k in pairs(self) do print("EventD_postInit, class nil", i, k) local meta = getmetatable(self) print_r(meta) end end   self._proxy = newproxy(true) getmetatable(self._proxy).__gc = function() self:_destroy() end end </end>

Any smart advice on how I could get it?

Thank you!
