It appears the problem existed before the lila3 was deployed on 11/22. If you notice the GC graph. The number of GC cycles/minute kept increasing gradually starting on 11/10 and almost doubling on 11/21. The 11/22 deployment of lila3 reset the graph and since you have been restarting everyday since, we can't see the growth of more than a day. My wild hunch is a code push on 11/10 causing a memory leak, worth checking in my opinion.
