我有一台在 Netty 上工作的服务器。客户端发送一些握手消息和服务器回复。这些是小消息，这些没有问题。
但是，当服务器尝试发送一些大消息（每个大小为 131139 字节）时，似乎它们正在被发送ChannelFuture，isSuccess()返回true和getCause()返回null。但是，客户端永远不会得到完整的消息，只有第一4097条消息的第一个字节。在 4 或 5 条消息之后，netty 停止尝试发送新消息。
我isWritable()在发送消息之前正在阅读频道（它总是返回true）。仅当 的 被触发时才会尝试下一条operationComplete消息ChannelFutureListener。将消息写入通道后，日志显示“INTEREST_CHANGED”事件被抛出两次，并且isWritable更改为false，然后立即更改为true。但是消息永远不会到达客户端。

谁能告诉我为什么消息没有通过？
更新：它实际上是第一条消息的 4097 字节。我没有计算标记数据包长度的前 4 个字节。
更新：如果传出数据包长度小于或等于 4097 字节，则一切正常。仅当数据包大于 4097 字节时，Netty 才会中断。它是 4097，而不是 4096。它会响铃吗？
