Previously, when an existing cache entry was updated, we didn't update the atime. Subsequently, when the entry was removed, we never cleaned the orphan atime entry. During trimming, we traverse the atime entries, and since the orphaned one didn't have any matching objects or ctime entries, the ets_lru cache would crash, possibly taking down the primary couch supervisor.
