[Zope-dev] Maxinum number of versions for a single object in the ZODB ?

Yo, Somewhere in our deployment we have a SimpleItem.SimpleItem object with a random number generator in it. The code to get a new random number is: random=self.__random.random() #.... self._p_changed = 1 # make sure to store the changed generator We use that generator A LOT, but today, after some months of working correctly, it just stopped returning different random numbers. I have no other clue than to guess there is a maxinum number of different versions any object can have in the ZODB. Is my hunch correct ? TIA, Romain.
