推荐答案

高于 127 的退出代码通常意味着由于 信号.

Exit codes above 127 typically mean the process was stopped because of a Signal.

退出代码 137 然后解析为 128 + 9，而信号 9 是 SIGKILL，即进程被强行杀死.这可以是一个kill -9"命令.但是，在您的情况下，这可能是操作系统内存不足的情况，这会导致名为OOM Killer"的功能停止使用大部分内存的进程，以保持操作系统本身稳定，即使在这样的情况下条件.

The exit code 137 then resolves to 128 + 9, whereas Signal 9 is SIGKILL, i.e. the process was forcefully killed. This can among others be a "kill -9 " command. However in your case this could be an out of memory condition on the operating system, which causes a functionality called "OOM Killer" to stop the process which is using up most of the memory in order to keep the OS itself stable even in such a condition.
