Look at the command "nice" to see if that will help.

I've noticed on lower-end systems, that daily cron will peg a system

installed that the apt update would hang the system for like a
half-hour with an old 400mhz ppc proc, consuming all cpu and memory,
then swap and thus disks too.  I finally just disabled it, and shortly
thereafter retired the outdated system itself that it obviously had
outlived its usefulness vs. power drawn.

You likely have the same issue, just when using it, the update will
slam the system.  Might be better off doing it manually, or setting
the update time for the cronjob to overnight when not using it.

the problem seems to have been checkapt.py . I tried to figure out what it does and it seems that it locks a database (apt's?). But it couldn't of been apt's as I wasn't running apt. Then I ran top again and it seemed to have corrected itself after 10 or fifteen minutes. Am I correct in what I think it does? Is it safe to kill if this happens again?
