Question

您好我使用以下队列版本

chronicle-queue.version : 4.5.15
chronicle-wire.version : 1.7.14

My Chronicle读者在某些时候陷入困境（索引74204158352345），readDocument在每次调用后返回false，但我的编年史编写者继续将消息写入同一队列。读者代码如下，

ChronicleQueue queue = ChronicleQueueBuilder.single(chroniclePath).build();
excerptTailer = queue.createTailer();
excerptTailer.readDocument(document);// Marshallable document

我在while循环中调用readDocument。日志中没有编年史错误。但是我的代码会对编年史队列中的最后一条消息进行制动，因为消息不完整。我只获得了最后一条消息的一些字节，并且在readDocument之后返回false。但是有消息不断写入队列。

我的作家代码，

public void init() {
    queue = ChronicleQueueBuilder.single(chroniclePath).build();
    appender = queue.acquireAppender();
}

public void write(T document) {
    appender.writeDocument(document);
}
public void destroy() {
    if (queue !=null && queue.isClosed()) {
        queue.close();
    }
}

我尝试将队列升级到本地计算机中的最新版本（4.5.27 & 1.7.32）并再次在同一个生产cq4文件（5GB）上运行读取器我遇到了同样的问题，但在控制台上出现错误（锯螺纹转储中的相同线索也是如此）

etc...

在新版本中，readDocument方法挂起。可能挂在递归上。可能是什么问题，请帮忙。

Chronicle队列读取器（ExcerptTailer）不会读取消息，即使队列中有很多消息也会返回false
