pm2 dump loses all entries after unexpected reloading

[denisenkoaj]

What's going wrong?

pm2 have no entries about my processes

How could we reproduce this issue?

When something happens unexpectedly that restart pm2 process. For example free disk space runs out.

I've tried to add flag +i to pm2 dump, but it blocked Keymetrics online monitoring
