Cause

PowerProtect 数据保护存储设备使用 PostgreSQL 来执行一些内部功能。由于运行的 Postgres 进程过多，并且重复的内核进程条目淹没了 /var/log/messages 文件，因此存在内存耗尽问题。有一次，有 422 个 Postgres 进程使用 PowerProtect 数据保护存储设备上的 15 GB 内存。Postgres 条件导致 /var/log/messages 文件在 ~14 小时内消耗剩余磁盘空间（例如 11G）。

Resolution

PostgreSQL 问题已在 PowerProtect Data Manager 19.16.0-15 或更高版本中得到解决。安装最新的 PowerProtect Data Manager 版本以解决此问题并防止根分区被完全使用。

PowerProtect Data Manager 驱动程序和下载页面上提供了最新版本。

解决方法
删除现有的 /var/log/messages 并重新启动 PowerProtect 数据保护存储设备，以释放文件占用的磁盘空间。
