Description kavol 2007-12-06 20:56:33 UTC

Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc version 4.1.2 (Gentoo 4.1.2 p1.0.1) 
OS:                Linux

when running a single application - konqueror in my testcase - some necessary KDE stuff is run on the application startup

however, these processes keep running long after the application is closed (I closed konqueror right after starting it) - see below

kika      6844  6631  0 20:34 pts/8    00:00:00 grep --colour=auto kika

they do not disappear even after completely logging out the user:

root     15569 19785  0 20:52 pts/5    00:00:00 grep --colour=auto kika

I guess it is intended to let them run for some time to speed-up the next KDE application startup, but tenths of seconds, minutes at most, would be more realistic - not hours or "forever"

I have found one similar case, bug 82998, but I guess it has nothing common from the system point of view

Comment 1 Médéric Boquien 2008-11-08 22:16:53 UTC

Hello,

This problem should have been fixed some time ago. Can you try with the latest KDE version and report if this bug is still present for you?

Thanks.

I have some troubles compiling and running the newer version

I'll report back ASAP (let's say Dec 7 at latest)

Comment 3 FiNeX 2008-11-24 16:55:14 UTC

Many thanks Kavol, we'll wait your feedback :-)

Comment 4 kavol 2008-12-06 18:43:10 UTC

unfortunately, I still observe this behaviour with KDE 4.1.80

I started the test logged in as user "test" with no processes belonging to the user "kavol" running:

test@kika ~ $ date; ps -ef | grep kavol                                       
So pro  6 17:43:15 CET 2008                                                   
test      8436  8085  0 17:43 pts/0    00:00:00 grep --colour=auto kavol

in another konsole tab, I used su to become user "kavol":

test@kika ~ $ date; ps -ef | grep kavol
So pro  6 17:43:24 CET 2008

test      8448  8085  0 17:43 pts/0    00:00:00 grep --colour=auto kavol

as user "kavol", I launched konqueror:

after trying to log out, the ssh session hangs, and from another terminal I can see processes still running:
jarmilka ~ # ps -ef | grep pes

after killing the ssh session with Ctrl+C, the rest of processes belonging to that user disappears ... not nice if I'd like to use it in a script (not to talk about the wasted resources while no KDE application is running ...)

... forgot to change status (hey, bugzilla should do that automatically if info is provided) ...

I don't suppose this is still happening in a recent version of Plasma 5, is it?
