ps lookup returning false data

[ssk199441]

I use ps-node to check if a process is still running and if not restart it. Every now and then it returns an empty array without an error. At the end of a day, about 3 processes are running. I didn't find a workaround yet

Confirming.
ps-node isn't finding anything either by pid or command name or regexp.

Platform: Linux Kubuntu 22.04
