Cause

PowerProtect 裝置使用 PostgreSQL 執行部分內部功能。出現記憶體耗盡問題，因為執行中的 Postgres 程序過多，且重複的核心進程項目充滿 /var/log/messages 檔案。其中一個實例中，PowerProtect 應用裝置上有 422 個使用 15 GB 記憶體的 Postgres 程序。Postgres 狀況導致 /var/log/messages 檔案在 ~14 小時內消耗剩餘的磁碟空間（範例為 11G）。

Resolution

PostgreSQL 問題已在 PowerProtect Data Manager 19.16.0-15 或更新版本中解決。安裝最新的 PowerProtect Data Manager 版本以解決問題，並防止根分割區遭到完全使用。

PowerProtect Data Manager 驅動程式與下載頁面提供最新的可用版本。

因應措施
刪除現有的 /var/log/messages，然後重新啟動 PowerProtect 裝置，以釋放檔案佔用的磁碟空間。
