Massive memory leak when upgrading from 4.3.2 to 4.8.2


About three weeks ago, I upgraded from 4.3.2 to 4.8.2. Since then, we have seen a massive spike in memory usage, causing the service to run out of memory approximately every week. Otherwise, our memory usage was fairly stable over the last two years.
