我正在使用编年史地图 v3.10.1。在我的地图中，我有大约 77K 条目。我正在尝试使用entrySet()方法遍历此地图。它没有成功迭代，并且在抛出 Chronicle 特定异常之间。以下是 Chronicle Map 产生的日志

016-09-17 06:39:15 [ERROR] n.o.c.m.i.CompiledMapIterationContext - Contexts locked on this segment:
net.openhft.chronicle.map.impl.CompiledMapIterationContext@205cd34b: used, segment 62, local state: UNLOCKED, read lock count: 0, update lock count: 0, write lock count: 0
Current thread contexts:
net.openhft.chronicle.map.impl.CompiledMapIterationContext@205cd34b: used, segment 62, local state: UNLOCKED, read lock count: 0, update lock count: 0, write lock count: 0

和例外：

2016-09-17 06:39:15 [ERROR] akka.dispatch.TaskInvocation - Failed to acquire the lock in 60 seconds.
Possible reasons:
 - The lock was not released by the previous holder. If you use contexts API,
 for example map.queryContext(key), in a try-with-resources block.
 - This Chronicle Map (or Set) instance is persisted to disk, and the previous
 process (or one of parallel accessing processes) has crashed while holding
 this lock. In this case you should use ChronicleMapBuilder.recoverPersistedTo() procedure
 to access the Chronicle Map instance.
 - A concurrent thread or process, currently holding this lock, spends
 unexpectedly long time (more than 60 seconds) in
 the context (try-with-resource block) or one of overridden interceptor
 methods (or MapMethods, or MapEntryOperations, or MapRemoteOperations)
 while performing an ordinary Map operation or replication. You should either
 redesign your logic to spend less time in critical sections (recommended) or
 acquire this lock with tryLock(time, timeUnit) method call, with sufficient
 time specified.
 - Segment(s) in your Chronicle Map are very large, and iteration over them
 takes more than 60 seconds. In this case you should
 acquire this lock with tryLock(time, timeUnit) method call, with longer
 timeout specified.
 - This is a dead lock. If you perform multi-key queries, ensure you acquire
 segment locks in the order (ascending by segmentIndex()), you can find
 an example here: https://github.com/OpenHFT/Chronicle-Map#multi-key-queries

它是一个单线程和持久化的映射。
