我一直在服务器日志中看到以下警告和堆栈跟踪，并且想知道出了什么问题以及如何解决它。我检查了名称 PUSH-000183，但它只显示“消息通道发生通信错误”。

这是否仅限于使用 XHR 连接的客户端，还是 websockets 也会受到影响？

当客户端向服务器发送的消息大于Connectors.xml中配置的输入缓冲区大小时，就会发生这种情况。

它将断开客户端的连接，如果它已被配置为重新连接，则该客户端可能会重新连接。无论传输方式如何（XHR、Websockets 等），任何客户端都可能发生这种情况。

您将需要增加Connectors.xml中的输入缓冲区大小以匹配您期望的最大消息。例如，如果您发送的消息最大为 256K，您可以使用以下配置：

<socket-conditioning>
     <!-- If this value is less than max-message-size defined in 
          Server.xml, it will be
          overwritten by the latter. -->
     <input-buffer-size>256k</input-buffer-size>
     <!-- Other config... -->
</socket-conditioning>
