CacheCloud Master 版本(支持密码),发现OOM ， DUMP 分析结果如下： Class Name | Objects | Shallow Heap | Retained Heap

DATA_COST_TIME_MAP_ALL 定义如下： private static ConcurrentHashMap<CostTimeDetailStatKey, AtomicLongMap> DATA_COST_TIME_MAP_ALL = new ConcurrentHashMap<CostTimeDetailStatKey, AtomicLongMap>();
怀疑是ConcurrentHashMap没有释放造成， 请大神确认下
