jenkins主连接失败，出现java.nio.channels.ClosedChannelException

我有一个每小时运行一次的作业，从一台主机（Ubuntu上的Jenkins）到作为从机的Windows10，30-40%的时间作业只是由于以下错误而失败。我需要一些帮助，从哪里开始寻找，或者有什么可能的解决方案

主服务器和从服务器都有相同的Java版本“1.8.0_151”

。。。最好的前进路径是创建一个git客户端身份验证令牌类，该类使用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git客户端身份验证令牌将通过导线从主机发送到代理，而不是通过导线发送机密

也许试着用一个新的

另外，我建议您将电子邮件从代码段中删除。这可能是由于内存错误造成的，如

中所述，这提示您什么？类似的尝试和错误体验。充其量只是轶事
