解决办法：

打开代理路径：例如E:\Jenkins_Slave_Home

在Jenkins Slave上找到jenkins的安装目录下面的jenkins-slave.xml文件，增加参数‘-Xmx1024m ’，然后重启jenkins agent服务，参数修改如下

<arguments>-Xmx1024m -Xrs  -jar "%BASE%\slave.jar" -jnlpUrl http://123.56.77.191:8080/computer/home_windows/slave-agent.jnlp -secret c51d49f492ba32dec9a20da86c0e919a663b5f6c6c5cd2a4c3583c48405e7a05</arguments>
