【问题描述】：

当我将我的项目上传到 Bitbucket 时，Jenkins 的管道会执行几个文件来检查我的更改是否没有破坏项目。主线是"stderr: Received disconnect from 10.34.6.240 port 7999:12: Too many concurrent connections (250) - max. allowed: 250"

所有错误：

git fetch --tags --progress ssh://git@bitbucket.tecnotech.com:7999/qat/sgi-linkingtool-web-test.git +refs/heads/*:refs/remotes/origin/* # timeout=10

【解决方案1】：

看来您需要增加plugin.ssh.session.max 的值。请参阅Bitbucket configuration manuall 中的相应部分。
