Hi, I met a bug.

I installed plasma-workspace-5.9.3-2.fc25.x86_64 from the copr, and in Xorg.

But I found in sometime, cpu load will be 100%, I often found one cpu is 100%.

PS: just before, I found wireshark is not-responding and one cpu is 100%, so I kill wireshark, All cpu is immediately 100%.

Check to see if you have any zombies.   You can do this easily using "top" from the command line.

If so, you can identify the zombies using:

ps axo stat,ppid,pid,comm | grep -w defunct

You will then get an output similar to this:

Z     2501 18728 xdg-user-dir <defunct>

The number following the Z is the parent process.

Then do:

ps -e | grep nnnn (in this case 2501)

The parent process will be either plasmashell or krunner

Then, restart either plasmashell or krunner by using krunner (alt-F2):

killall plasmashell; plasmashell
or
killall krunner; krunner

That should eliminate the zombie processes and put the cpu utilization back to normal.
