OpenVZ VPS无法启动SSH的问题谁遇到过？

[andybest]

一个Ramnode的128M SSD VPS，两天前自动重启了SSH就无法连接了
连安装了DropBear都无法启动，启动后无任何错误信息，就是端口没有坚挺（尝试换了各个不同端口）
谁遇到过类似的问题？任何建议和回复一定感谢！

root@ssd:/# /etc/init.d/ssh start
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service ssh start

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start ssh
ssh stop/pre-start, process 581
