最近，我们开始遇到厨师客户在跑步过程中死亡的问题，因为我们在通常进行得更快的跑步列表的各个部分上花费了更多的时间。我使用的是家庭 Wi-Fi，而我的同事使用的是工作 Wi-Fi，该 Wi-Fi 本身也存在一些连接问题。
如果在 Chef-client 运行时您与计算机的 ssh 连接中断，是否会以看似莫名其妙的方式导致运行崩溃？我正在使用 PutTY 从 Win7 进行连接，而我的同事正在使用 Apple 终端应用程序。
我们运行此程序的所有机器都是 Ubuntu 12.04（在 EC2 中），并且有足够的剩余磁盘空间 - 它们仅使用 ~1GB 和 ~5GB 可用空间。
这是日志的输出/var/log/chef/client.log（设置与log_location指令中/etc/chef/client.rb as 此处描述 https://wiki.opscode.com/display/chef/Troubleshooting+and+Technical+FAQ#TroubleshootingandTechnicalFAQ-WherecanIfindChef%27slogs?).

这是一个非常普遍的错误！但它似乎确实表明 STDOUT 输出中断，这对于客户端断开连接来说是有意义的。
Edit:根据要求，现将内容介绍如下：client.rb文件（名称自然会被混淆。）
$ cat /etc/chef/client.rb
log_level :auto
log_location "/var/log/chef/client.log"
chef_server_url "https://api.opscode.com/organizations/myapp"
validation_client_name "my-validator"
node_name "my-app-node"
Edit 2:尝试使用sudo su -s /bin/bash root -c "screen chef-client"
当我吃午饭时，屏幕终止并记录了超时ShellOut命令为npm install。这是在厨师兼客户在这个操作上呆了一个多小时之后。

这是一个与之前完全不同的错误。这stacktrace.out文件还明确提到ShellOut，所以它也完全不同。最奇怪的是，当我从命令行运行相同的 npm 命令时，不到一分钟就完成了。
所以我不确定是否有办法进一步诊断之前的故障，但我欢迎其他建议。对于这个新的失败的意见，我问这个后续问题 https://stackoverflow.com/questions/21032634/chef-client-hanging-on-npm-install-at-node-gyp-rebuild.
