For a couple days now, I notice a process called pmproxy using 100% CPU on bootup and stays at 100%. I kill the process and it restarts a couple seconds later. I renamed the folder /usr/lib/pcp and that got it to stop restarting.

I don't remember installing or downloading anything like that. Is it malicious?

I'm using Ubuntu 20.04 LTS with latest updates.

  • I'd run a malware scan and see what turns up. I'm not familiar with that pmproxy, but something that uses 100% CPU and auto restarts is certainly suspicious at best. I'd run a malware scan, and if it does turn out to be malware, have an offsite isolated backup of anything important if you don't already – cocomac Mar 25 '22 at 04:42

    The pmproxy package is for performance metrics collection and is installed as part of the Performance Co-Pilot (PCP) toolkit. If your machine is a VPS, then it was likely installed as part of the base installation package from the provider. There may be a reason for the CPU consumption recorded in the /var/log/syslog file, so you'll want to check in there to see what might have triggered the issue – matigo Mar 25 '22 at 04:52

I had the same issue due to cockpit-pcp removing both resolved the issue for me (as cockpit-pcp is not important for me on my laptop)

sudo apt remove pcp
