如何防止jenkins日志被奇怪的消息发送垃圾邮件

Question

几乎每周我们运行jenkins的开发服务器都没有剩余磁盘空间,因为jenkins日志文件变得很大(> 100g).它被这些奇怪的消息完全填满:

[DNSQuestion@1218458593 type: TYPE_IGNORE index 0, class: CLASS_UNKNOWN index 0, name: ]
    [DNSQuestion@1577918927 type: TYPE_IGNORE index 0, class: CLASS_UNKNOWN index 0, name: ]

我们正在运行当前的Jenkins版本1.622.

Answer 1

这是Jenkins依赖的已知问题,跟踪为JENKINS-10160(尽管问题跟踪器在撰写本文时已关闭).

如果您没有使用Jenkins的DNS服务发现功能(您可能不是),那么您可以在启动Jenkins时使用以下命令行标志禁用此功能:

-Dhudson.DNSMultiCast.disabled=true -Dhudson.udp=-1

Answer 2

我有同样的问题,我用克里斯托弗的解决方案解决了这个问题.我在Ubuntu 14.04上运行jenkins.我修改了我的/ etc/default/jenkins文件,修改了JAVA_ARGS

JAVA_ARGS="-Djava.awt.headless=true -Dhudson.DNSMultiCast.disabled=true -Dhudson.udp=-1"

然后重新启动jenkins
