PUSH-000183：处理程序在缓冲区中没有留下 space

Question

我一直在服务器日志中看到以下警告和堆栈跟踪，想知道出了什么问题以及如何解决。我检查了 the designation PUSH-000183，但它只显示 "A communication error has occurred on a message channel."

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

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

它将断开客户端连接，如果已配置，则客户端可能会重新连接这样做。无论传输方式如何，任何客户端都可能发生这种情况（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 的消息你可以使用下面的配置：

<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>
