      NEWER than swap file!

(1) Another program may be editing the same file.
    If this is the case, be careful not to end up with two
    different instances of the same file when making changes.
    Quit, or continue with caution.

(2) An edit session for this file crashed.
    If this is the case, use ":recover" or "vim -r alert_PROD.log"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file ".alert_PROD.log.swp"
    to avoid this message.

Swap file ".alert_PROD.log.swp" already exists!

Study

此現象與用 vi alert_PROD.log  時，未結束此 Processs 就關機，而發生此異常現象。

Solution

若只是查看，直接刪除此 swap 檔案  .alert_PROD.log.swp 即可。
