perhaps you have a permissions problem using the command as "user".  ????

Hi Patrick, thank you for responding, I will intersperse my replies within your responses so as to keep this organized.  Hmmm I am not sure what you are referring to here, but guessing here is the permissions for the sto relevant commands:

nova:/etc/systemd/system # which kquitapp5
/usr/bin/kquitapp5
nova:/etc/systemd/system # ll /usr/bin/kquitapp5
-rwxr-xr-x 1 root root 14888 Aug 26  2021 /usr/bin/kquitapp5
nova:/etc/systemd/system # which kstart5
/usr/bin/kstart5
nova:/etc/systemd/system # ll /usr/bin/kstart5
-rwxr-xr-x 1 root root 44256 Aug 26  2021 /usr/bin/kstart5

file:///usr/share/plasma/plasmoids/org.kde.plasma.pkupdates/contents/ui/Full.qml:278:9:

QML BusyIndicator: Detected anchors on an item that is managed by a

t. This is undefined behavior; use Layout.alignment instead.

Note: I was unable to run these commands as root, I get the following error
message if I try -

# kquitapp5 plasmashell && kstart5 plasmashell
"Application plasmashell could not be found using service
org.kde.plasmashell and path /MainApplication."

this would indicate to me that "plasmashell" was not running, thus the
command cannot stop it and the following kstart5 command depends on the
previous command being successful.
 

This did not help with the system slowdowns I am experiencing on one of my
systems either.

Any more ideas, I appreciate the thoughts given , thank you. Marc

first determine that plasmashell is actually running,
  ps aux |grep plasmashell

if not, you can start it:
  kstart5 plasmashell

nova:/etc/systemd/system # ps aux | grep plasmashell

ps: your sig is trash and has worthless, uninforcable legal ramifications. 
junk!

My sig is mostly meant to be humorous, there is no legal notifications within it. There is some Morse code for fellow amateur (ham) radio operators to have fun decoding, and some explanation of the attached digital signature key. Sorry if you found it confusing and not obvious! Thanks again so much for helping me try to solve these system slowdowns I am experiencing.

One more  item of note, trying to use x11vnc service on the machine that is experiencing a slowdown, and then connecting in to it remotely from another machine using vncviewer is next to impossible! Then the response times become excruciatingly slow, up to 5 minutes or more and sometimes it just crashes the remote system..
