我在运行我的 Rails 网站时遇到以下错误，我相信它会导致它崩溃。我正在使用Passenger，我的网站流量很大。当我试图让它重新上线时，Apache 产生了大量的子节点，机器上的负载飙升到 50 左右，网站变得非常缓慢。我不缺磁盘。

PGError (FATAL:  could not access status of transaction 0

“设备上没有剩余空间”错误不一定是由空间不足引起的。它也可能是由文件系统的 inode 表填满引起的 - 换句话说，您的文件系统只能容纳这么多文件，而您已经达到了这个限制。

如果您有大量小文件，则可能会发生这种情况。在这些情况下，通常会使用大型 inode 表构建新文件系统，以允许更多数量的小文件。

Another possibility would be per-user disk quotas - see http://www.postgresql.org/docs/8.4/static/disk-full.html
