✅可能原因与对应处理
| 原因 | 说明 | 解决方式 | |
|---|---|---|---|
| 1. 大文件或提交过多 | 你这次推送了 37 个对象，虽然不算特别大，但如果包含大文件（如 PDF、图片、jar 包），容易触发 GitLab 的限制。 | 检查是否有大文件被提交： `git rev-list --objects --all | grep -E '.(pdf|jar|zip|png|jpg)'<br>如有，用git filter-repo或BFG` 清理历史。 |
| 2. 网络不稳定 / VPN 中断 | 你公司 GitLab 地址是gitlab.hezhihulian.com，可能是内网或 VPN 环境，连接中断。 | 重试几次：git push origin dev_tianzhi或换网络 / 换 SSH 端口。 | |
| 3. GitLab 服务器限制 | 服务端配置了超时或最大包大小限制（如 Nginx、GitLab 本身的git timeout）。 | 联系运维确认 GitLab 日志/var/log/gitlab/gitlab-workhorse/current是否报错。 | |
| 4. SSH 密钥或权限问题 | 虽然报错不是权限拒绝，但某些 GitLab 版本在权限异常时会直接断连。 | 确认你有dev_tianzhi分支的推送权限，且 SSH key 已正确配置。 |
你可以立即尝试的排查/修复步骤
重试推送（最简单）：
git push origin dev_tianzhi减小包大小（分批推送）： 如果你本地有多个提交，可以尝试分批次推送：
git rebase -i HEAD~10 # 把多个提交合并成1~2个 git push origin dev_tianzhi使用 HTTPS 推送测试（排除 SSH 问题）：
git remote set-url origin https://gitlab.yang.com/xxx/xxx.git git push origin dev_tianzhi检查是否有大文件：
git ls-tree -r -l dev_tianzhi | sort -k4 -n | tail -10
