SUMMARY
***

Yesterday I was doing a test unpacking and copying large files (.tar.zst) 57gb+
with tar and zstd, using local HDD and from HDD to HDD (2x1TB WD Caviar Black)
using ...

Operating System: Fedora Linux 35
KDE Plasma Version: 5.23.3
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2
Kernel Version: 5.15.6-200.fc35.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i7-3770K CPU @ 3.50GHz
Memory: 15.6 GiB of RAM
Graphics Processor: AMD Radeon RX 580 Series 

and I noticed a very big inconsistency in the system since random program
endings during the process of copying or unzipping such as dolphin, konsole
telegram and etc., performing both copying and unzipping via terminal or via
dolphin where the problem is bigger. The same tests were carried out within
IceWM and Alacritty on the same computer and no problem was observed, just a
natural slowdown in the process of using the disks.

***

STEPS TO REPRODUCE

1.  Catch a big file 56gb + .tar.zst
2.  Open the Dolphin and launch some programs like telegram, konsole, ..., try
to copy or decompressing the file to the same HDD 7200 RPM or to another HDD
7200 RPM
3. Try the same process using the Konsole with $ tar xf <file> and cp -rf
<file> <destiny>

OBSERVED RESULT

The copy or decompress fail using Dolphi or Konsole and the DE crash and
restart itself.

EXPECTED RESULT

No crashes in DE and a copy or decompress with success using the Dolphin or the
terminals.
