All applications disappeared. pm2 list displays empty list #4798
Description
What's going wrong?
I used pm2 for months, and yesterday all applications disappeared. It happened suddenly - I didn't reboot my computer, didn't create any new applications - just reviewed logs. At some point, when I ran pm2 list it displayed empty list. I waited for some time (I remember early I had similar behavior right after the computer reboot and had to wait some time) - no, after few hours it's still empty.
How could we reproduce this issue?
Not sure.
