Your simulation of cim aging is perhaps excessively powerful, because it's sent my city into a ridiculously unstable state. I have checked for every other potential issue and there is nothing else that could be causing this.

At one point, I had huge population growth because I zoned a large residential area at once. This was accompanied by huge numbers of adult cims moving into the city and a corresponding huge number of births. Then, approximately 2 years later, all these cims die. This then means there is another large residential area for people to move into and the cycle begins again but worse.

Proof of theory:

Here's an example of city demographics during a crash. Note the massive weighting towards the upper end of the age range: http://i.imgur.com/CTaZx8w.jpg

It's severe enough for my city to enter the red at the bottom of a population crash. The streets empty, traffic near totally disappears, industrial districts become abandoned due to lack of working age population. During booms, the schools and universities become overloaded to the point where the education system actually becomes responsible for traffic gridlock. Note that issues that happen during these booms are not actually severe enough to be causing the population collapse.

So what makes this a bug (or at least a problem)? There is, as far as I can determine, no way to actually end this demographic tsunami once it begins. I can still play the game and I have been doing significant city building, but it becomes much more difficult to deal with traffic problems appropriately since I have near-zero traffic during collapses and the real problems only show up during the peak. I will update this post as my waves continue.
