Syslog 產生數百行

我最近被“提升”為實驗室管理員，因為我對 linux 有最豐富的經驗。我的 logcheck 不斷向我發送電子郵件，其中包含來自我的syslog文件的數百行。它重複自己，每次都有微小的變化。我不知道它想告訴我什麼。有任何想法嗎？這是一個重複的片段：

您看到的是堆棧跟踪。這是一個來自核心的未處理錯誤，它顯示了執行路徑，當某些事情變得如此糟糕以至於除了記錄問題並將其留給人類解決之外別無他法。

頭部的呼叫通常是定義性的：

WARNING: at /build/buildd-linux-2.6_2.6.32-45-amd64-FcX7RM/linux-2.6-2.6.32/debian/build/source_amd64_none/fs/fs-writeback.c:588 writeback_inodes_wb+0x36b/0x4ff()

fs-writeback: 那是寫入文件系統。正如對您的問題的評論中指出的那樣，您的磁碟上可能有錯誤。我首先將機器置於具有隻讀掛載和執行的單使用者模式fsck。
