我正在按照本指南将我的站点迁移到一个新的 Droplet：

Prepare new VPS First, prepare our new Current Ubuntu LTS VPS with empty Discourse dir, OS upgrade and Docker install sudo mkdir -p /var/discourse sudo apt-get update sudo apt-get dist-upgrade wget -qO- https://get.docker.com/ | sh Then, make sure that we are on latest installed kernel and other libraries by just restarting …
我已到达需要重建的阶段，它运行了一段时间，然后出现了这个：
```plaintext

2933:C 21 Dec 2023 17:29:25.583 * DB saved on disk

查看旧帖子，其中提到了这个问题，大多数建议都集中在重启 VPS 并重试命令。我这样做了，但问题没有解决。我现在已经运行了三次重建，结果如下：
1. 重启后没有返回
2. 等了一个小时，终于发生了以下情况

1. 运行了一个小时后，我收到一个“broken pipe”错误并断开连接
有什么线索可以指导我如何继续吗？
这个 droplet 是 2G RAM / 50G 磁盘，运行 Ubuntu 23.10 x64。rsync 命令似乎按预期运行。
谢谢！

我认为错误 137 是内存不足。您是否设置了足够的交换空间？

啊，原来是这样，我没有设置交换空间。谢谢，现在一切都正常了。
