See the discussion here: https://github.com/overhangio/tutor/pull/984 And the upstream PR here: https://github.com/openedx/edx-platform/pull/34210 The tl;dr is that the Redis course structure cache was growing without bounds. While the upstream fix should resolve that issue, we decided that Tutor should have a maxmemory limit and an eviction policy set for operational safety. Thus, Redis now has a 4gb maxmemory. If you need more memory on your instance, you should implement the "redis-conf" patch. To manually expire existing keys, run: tutor local run cms ./manage.py cms shell -c "from django.core.cache import caches; c = caches['course_structure_cache']; [c.expire(key, 604800) for key in c.keys('*')]"
