pm2 Multiple God Daemons and node process Spawning

ng flag
Sterina Pen

I Have node apps unning using pm2.And it is spawning multiple pm2 daemon instead of one which is eating up all the memory.

When I run ps aux | grep pm2 Command I see multiple God daemons for the pm2 process instead of one. I have a total of 10 pm2 processes for which there should be only one God Daemon. I have installed pm2 globally and it is running by user appuser. Can anyone tell me how can I fix this?

Why do you use pm2? You could just start your app from systemd directly.

We manage the node service with pm2, and we manage pm2 via a init.d service file which is located at /etc/init.d/service-file.

We fixed the above issue by removing the update-rc.d entries for pm2 services which were causing the extra node and pm2 process to start. Also to start the services at reboot, we added the start script in cronjob.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
