CPU usage problems on my VPS again
As reported previously, I had problems with the CPU usage on my VPS again, even after namespace isolation. This time, it was dnsmasq causing the loadavg to rise. “This is a problem for future me to solve properly”, is the motto. For the time being, I simply added a service restart when I detect a high loadavg. Works well enough. I’ll keep monitoring it to see if this occurs more than once a week or so.
