是什么杀死了我的程序，为什么? [英] What killed my process and why?

问题描述

我的应用程序在Linux上作为后台进程运行.当前是在终端"窗口中的命令行启动的.

My application runs as a background process on Linux. It is currently started at the command line in a Terminal window.

最近，用户在执行该应用程序一段时间后，它神秘地死了.文字:

Recently a user was executing the application for a while and it died mysteriously. The text:

杀了

在终端上.这发生了两次.我问其他终端是否有人使用kill命令来杀死进程?不.

was on the terminal. This happened two times. I asked if someone at a different Terminal used the kill command to kill the process? No.

在什么条件下Linux会决定终止我的进程?我相信外壳程序显示为"killed"，因为该进程在收到kill(9)信号后就死了.如果Linux发送了kill信号，那么系统日志中是否应该有一条消息说明为什么它被杀死了?

Under what conditions would Linux decide to kill my process? I believe the shell displayed "killed" because the process died after receiving the kill(9) signal. If Linux sent the kill signal should there be a message in a system log somewhere that explains why it was killed?

推荐答案

如果用户或sysadmin没有终止内核可能拥有的程序.内核只会在极端的资源匮乏(例如内存+交换耗尽)之类的特殊情况下终止进程.

If the user or sysadmin did not kill the program the kernel may have. The kernel would only kill a process under exceptional circumstances such as extreme resource starvation (think mem+swap exhaustion).
