Question

我们遇到了“发布保证的消息发布”错误，它报告：

[ERR] {"message":"Guaranteed Message Window Closed","name":"OperationError","subcode":22,"level":"error","stack":"OperationError: Guaranteed Message Window Closed\n 
    at PublisherFSM.prepareAdMessageAndSend (/home/vcap/deps/0/node_modules/solclientjs/lib/solclientjs-debug.js:21530:13)\n

由于客户端已知的原因挂起了许多未确认的消息（默认窗口大小为50）https://solace.com/blog/understanding-guaranteed-message-publish-window-sizes-and-acknowledgement/。每次检查日志后，应用程序方在发布以解决问题超过1秒后都可以收到确认通知。

那么引入的solace服务器不能在客户端确认这么多消息的根本原因是什么？我们检查了客户端应用程序日志，然后发现以下与安慰相关的错误：

我们使用了solclientjs 10.2.1和Solace VMR 9.0.0.17。

我们只能重新启动客户端应用程序，但是那些未确认的消息会丢失。
