Python 使用了將近 30% 的 SWAP 文件，而且它越來越大。可能沒問題，但是當 SWAP 文件大於 40% 並且臨時我無法更改它時，我的組織中有人設置通知，但我一直收到來自該伺服器的警報，這很煩人。

該伺服器上安裝了 Bitbucket、PostgreSQL 和 Apache。我試過swapoff -av && swapon -av了，但幾個小時後它又恢復到以前的大小，而且越來越大。

問題是在該伺服器 Python 程序上使用什麼？我確定 Bitbucket 或 PostgreSQL 沒有使用它，但看起來它與外部伺服器進行了某種網路通信（我們公司的 Bitbucket 也可以從外部站點獲得），因此它可能與 Bitbucket 結合使用。

那個過程是為了什麼？我可以以某種方式限制它嗎？

附言

當然我可以擴展 SWAP 但出於好奇我需要知道它是什麼？
