我每小时都有一个Job，从一个Master（Jenkins on Ubuntu）到windows-10 machine as slave，30-40％的时间作业失败并出现以下错误。我需要一些帮助，从哪里开始寻找或者可能的解决方案。
Master和Slave都有相同的Java版本＆＃34; 1.8.0_151＆＃34;

看起来您在虚拟从站上使用机密凭据时可能会遇到问题。
来自Here：
...最佳路径是创建一个git客户端身份验证令牌类，它使用AuthenticationTokens.convert（）将特定凭据（用户名/密码或ssh私钥）映射到git客户端，然后该git客户端身份验证令牌将通过电线从主人发送给代理人，而不是通过电报发送秘密。
也许尝试使用credential plugin？
我也建议您从摘录中删除您的电子邮件

这可能是由于this bug中所述的内存错误
