I have left my laptop on overnight for charging two video recording devices via USB. Next day I woke up, I found that there was heavy CPU, ram, and swap usage (screencap for reference).

In System Monitor, I saw that two systemd-udevd processes (see screencap) were running in the background. What could be the potential causes?
