SOFTWARE/OS Installed: openSuse Tumbleweed 20190527, KDE Frameworks 5.58.0, Qt 5.12.3 Affected: ktorrent (5.1.1), akregator (5.11.1), krename (5.0.0) and possibly more. PROBLEM If I close the program window (GUI) via the menu with "File -> Quit", in some cases, according to "top,", the associated process continues running (without being recognized as a "zombie"). A "killall PROGRAMNAME" on the cl then works. I have over the weeks noticed these continuing processes with * ktorrent (continues sending tracker requests) * akregator * krename but not systematically looked for this, <em>nor does it happen every time.</em> Given the previous discussion at https://linux-club.de/forum/viewtopic.php?f=93&t=122810 the described behaviour may be considered a feature by some people. <em>I consider unwanted network traffic a risk.</em> (Quote: “About a year ago, a dedicated programmer published a library that lets applications just get rid of their skin”) I also do have reasons to definetly wanting to end a program to free memory and limit load on MY machine! Specially torrenting with a laptop in somebody else's network is an absolute no-no. akregator's http.so requests also may leak information. REPRODUCE (using KDE on Linux): * run "top" in one console * restart "plasmashell" (killall plasmashell && plasmashell) in another console: this will show for example continuing UTP tracker requests (if ktorrents quits properly the message "Saving list of peers to /home/SOMWHERE/tor6/peer_list" is shown) * Quit kTorrent/akregator/krename by using the menu File --> Quit and watch the above
I encountered the same problem with konqueror on kubuntu 20.04 LTS. Close konqueror via the "X" button in the GUI but ps aux on the console still shows a running konqueror instance with sub-processes (e.g. http.so). Happens with konqueror 5.0.97.
