[PM2] [v] All Applications Stopped

What's going wrong?

I've deployed several applications using pm2, but at noon today I suddenly found a business exception, and using the pm2 list, I found that none of the applications in the list were present.
Check the logs:

journalctl -xe | grep pm2

What should I do to troubleshoot?

How could we reproduce this issue?

Supporting information

# Run the following commands
$ pm2 report

Start with the reported journalctl -xe | grep pm2 output and run pm2 report as requested. Trace why the PM2 daemon starts, deletes process id 0, stops all applications, and exits; the issue is complete only when the cause is identified and a reproducible troubleshooting path or fix is established.
