Question

我一直在服务器日志中看到以下警告和堆栈跟踪，并想知道出了什么问题以及如何解决它。我检查了the designation PUSH-000183，但它只是说“消息通道上发生了通信错误。”

这仅限于使用XHR连接的客户端还是websockets也会受到影响？

Answer 1

当客户端向更大的服务器发送消息时，会发生这种情况比Connectors.xml中配置的输入缓冲区大小。

它会断开客户端，如果客户端configured to do so，则可能会重新连接。无论传输如何，这都可能发生在任何客户端（XHR，Websockets等）。

您需要将Connectors.xml中的输入缓冲区大小增加到匹配您期望的最大消息。例如，如果你是发送最大256K的消息，您可以使用以下内容配置：

<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>

PUSH-000183：处理程序在缓冲区中没有留空间
