The MongoDB storage layer currently configures WiredTiger to keep idle collection and index handles open for 28 hours after the last use. We've seen cases where that leads to the WiredTiger handle list growing very large unnecessarily, which can introduce performance problems.
We should consider the consequences of reducing that time closer to the default value of 30 seconds.
