the relationship between metadata size and heap size

That sounds suspicious to me, not that after 16 thousand refresh cycles that you run out of memory (although that should be investigated), but that the refresh actually did anything.  So long as your web server is respecting the dates (preferably the ETAG too) there shouldn't be anything happening at the refresh.   So either that’s not correct, or it’s the act of checking to query the date that is leaking memory.
