PM2 with NodeJs crashing then restart every 1 second

I have a NodeJs+Express+Mongodb app and I'm trying to run it on my vps. There was a crashing problem with mongo so I removed "mongo.conf" file. Usually my app start crashing after few minutes. But after this change, everything was good for 24h then my server crash and restart every 1 second :

pm2.log (loop)

server-error.log (loop)

I don't understand what's wrong. Everything works fine on local. Every page works great online and suddenly everything crash and start reboot in loop ?

If that is an environmental variable not seen by your server application, try restart by refreshing with the following

pm2 restart server --update-env
