我在
Windows Azure VM上设置了Jenkins从属节点.在该节点上构建时,项目可以平稳运行大约20-30分钟,之后连接将被丢弃.连接被删除后,我一直在节点VM上,看起来它正在丢失/重置与Jenkins Master(也是Azure VM)的连接.有没有人有类似的问题,并能够解决它？堆栈跟踪如下.任何帮助,将不胜感激.

我也在Azure中设置了Jenkins CI并遇到了同样的问题.具体来说,我会在Jenkins从站错误日志中看到此错误：
SEVERE: I/O error in channel channel
java.net.SocketException: Connection reset
要解决此问题,您需要增加从站ping主站的频率.您可以通过将Dhudson.slaves.ChannelPinger.pingInterval系统属性添加到主jenkins.xml文件来完成此操作.
我修改它每2分钟ping一次,并且通道能够保持连接而不丢弃它. XML看起来像这样：
<arguments>
-Xrs -Xmx256m -Dhudson.slaves.ChannelPinger.pingInterval=2
-Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle
-jar "%BASE%jenkins.war"
--httpPort=8080
</arguments>
