Comment (by asn):

 Hm. To debug this we would probably need to make a tor patch that logs
 information about intro point creation and tear down. It should log
 everytime a new intro point is chosen, when one is expired, when it's
 added to the expire list and when it's removed from the expired list. We
 should also add log statements to `find_intro_point()` and its sister
 find_expiring_intro_point()` function. We might be able to accelerate the
 warning message trigger by reducing the intro point rotation period like
 dgoulet suggested.
