I have a question, I'm running a nodeJs server on a Digital Ocean droplet. I'm using pm2 for monitoring the application, everything looks fine. However suddenly, 100% of the CPU and memory were used by a process called rumpostgreswk screenshot of process. I killed the process but I don't know if it will come back again, as it happened during a night and was the first time. Can someone help me with this issue? Thanks in advance.
I think you should check the cron.
sudo crontab -u postgres -l
