My log PM2. Every second "Unknown id _old_1"

I have log files of 3GB. How to disable log message "Unknown id _old_1"?

I do not know, maybe after the restart.
$ pm2 report

I got the same issue.
pm2 kill took care of the dead process
pm2 kill works , but kills all process
I'm having this problem since updating to version 4. The only solution is to do this: pm2 kill && pm2 resurrect
I've set up a cron job that runs this every hour and that so far "solved" the problem. Hopefully, there is a fix soon

PM2 version : 4.1.2
Node.js version : 10.16.3
Current arch : x64
pm2 kill && pm2 resurrect
Thanks this fixed it for me when nothing else would.
