我可以使用CloudBees jenkins Enterprise来避免开源Jenkins的连接问题吗？

Question

我目前正在使用Jenkins open source edition 2.46.1，并且面临着JENKINS-28476连接问题。

我想知道使用Cloudbees Jenkins Enterprise是否可以避免这个问题？

我工作的公司愿意为商业软件付钱。

有没有人有过这样的经历？

在长时间(可能4-5个小时)的构建过程中，JENKINS-28476偶尔会出现在我们的机器上。

所以使用Cloudbees Jenkins企业版需要很长时间才能知道我们是否真的可以避免这个问题。

构建失败的错误消息如下：

其中192.168.123.123是从节点的IP地址。

看起来从主机到主机的连接中断了。

是的，与主服务器的连接已中断。CloudBees提供了诊断工具和支持服务来帮助您诊断这样的问题，这些问题通常是由环境因素引起的，比如网络设备中断通信。
