Hi,

I have used Konsole forever since the days of Mandrake 8.0.

But recently when i exit Konsole. It still show at 25% CPU usage in the process table, and 100% usage on 1 of the 4 CPU's.

And if i (open / exit) 3 more instance of Konsole, it will show 4 time 25% CPU usage in the process table and my 4 CPU's will each shows 100% usage, then a few seconds later the system crash.

I have seen this issues in recent install of Mint 18.3 (Cinnamon) and now in my everyday Mint 18.1 (KDE).

I installed other terminals, so it's not a real problem, but i am puzzled.

Google did not bring any answer.

I have not encountered this. I had one instance of konsole v. 2.14.2 running. I opened three more (I didn't do anything in them except run top), and, per top, CPU usage remained a 0.3%.

I can't duplicate this either...running Cinnamon on CentOS 7.5

In the screenshot i posted you will see a plasma applet showing 3 CPU's at 100% each. (if i try this with 4 CPU's my computer will crash).
And the system monitor/process table showing 3 instances of Konsole at 25% each (total CPU usage 75% just for Konsole).
I previously closed all those Konsole with the X button after running different little command. (lsusb, ect...)
When running a command the usage was normal and the command worked, when i exit Konsole it goes right to 25%.
I have seen the same thing on another fresh install Linux Mint 18.3 Cinnamon (different SSD drive.
Not a huge issue because i now use another terminal.
