PM2 在进程崩溃后启动一个新的守护进程并且不重新启动进程

Question

我的应用 "prod" 未在 SIGINT 上恢复。相反，PM2 会使所有其他应用程序崩溃并重新启动守护程序。

如果我关闭其他应用程序，它会正常工作：它们会自动重启。

我的日志如下所示：

这是我的 "prod"

生态系统文件

module.exports = {
  apps : [{
    name: 'prod',
    script: 'index.js',
    args: ["--color"],
    instances: 4,
    autorestart: true,
    out_file: "logs/prod.log",
    node_args: "--max-old-space-size=2048"
  }]
};

我的显示器看起来像：

请帮忙。这是一个大问题，因为它使我的服务器无法自动恢复。

我更新到最新版本的 PM2，但由于它触发了上述问题而降级。然而，它并没有改变任何东西

这个问题已经通过将 PM2 放入 docker 中得到解决。现在运行很顺利。检查 Docker 集成：https://pm2.keymetrics.io/docs/usage/docker-pm2-nodejs/

PM2 在进程崩溃后启动一个新的守护进程并且不重新启动进程

PM2 starts a new daemon after a process crashes and doesn't restart the processes
