Question
Gunicorn CPU usage suddenly increased to almost 100% since jan 20
- Posted January 23, 2021
- CentOS 8
Was there anything happened around Jan 20, @21:30?
CPU jumped from average of 30% to 60%, bandwidth jumpe3d from average of 15mb/s to almost 40mb/s. There wasn’t any change in my gunicorn configuration nor my application. I ran top command and found gunicorn consumed almost 100% cpu.

Hi @cpeters5,
It’s quite possible the traffic increased. Do you have any tools to monitor traffic coming to your application? I’ll suggest checking them out. That’s the first thing that comes to my mind if you haven’t made any other changes.
See if the CPU utilization is a 100% even after in the evenings when traffic should be lower. Again this should give you some information as to what is going on.
