2.? 原因猜測

? ? ?由于只有這些日志，只能針對報錯部分的代碼尋找原因。

? ? ?

? ? ?原因已找到，是由于代碼中出現了??System.exit(1);? 導致項目直接宕機了。

? ? ?4號發現已經改過了，為什么6號又出現了呢。因為沒有打新包。。。

當時看日志的時候，自以為是的找了一些關鍵字?

Stopping beans in phase 0.

but has failed to stop it. This is very likely to create a memory leak.

這些都不是根本原因啊....不過還是查到了一些東西...

最開始以為是OOM導致的宕機，各種看tomcat的鍋。以下是查到的資料。

Tomcat 8.5.38? ?
https://tomcat.apache.org/tomcat-8.5-doc/changelog.html
?Update the packaged version of the Tomcat Native Library to 1.2.21 to pick up the memory leak fixes when using NIO/NIO2 with OpenSSL. (markt)

修復了由于使用?NIO 連接 openSSL?時產生的內存泄漏。

而這個原因? but has failed to stop it. This is very likely to create a memory leak.

是由于項目停止時，連接池的連接沒有關閉。 忽略就好了，這個不是主要原因。

?
