SUMMARY I transfered serveral ISOs to my external HDD. Coincidentally I ran the systemmonitor, so I found out that a high CPU load caused the freeze. All 4 cores were at 100% while RAM stayed at 30% SOFTWARE/OS VERSIONS Linux/KDE Plasma: OpenSUSE Leap 15.2 (available in About System) KDE Frameworks Version: 5.7.0
What processes were consuming all that CPU?
