Tar of the valgrind debug logs.

SUMMARY

I am reporting this bug for dolphin in specified version which severely drains memory on a pretty fresh Kubuntu 25.10 installation. I see this error also with newer versions with KDE and plasma from the Kubuntu backports ppa. And I see a broader issue affecting other KDE software, especially under Wayland that I suspect related.

I examined the bug under Xorg, but I actually got to debugging dolphin because I am having generic issues that appear under Wayland. In the Wayland case the whole system, however, quickly gets so laggy that I cannot reasonably debug on it. 

Therefore, I suspect a larger underlying issue in some plasma or KDE frameworks libraries, but I am reporting for dolphin under X, because I cannot pin it down otherwise. Under X the service "kglobalaccel5" also eats memory, but that goes away restarting it after login. Dolphin, as a stand-alone application, is straight-forward to debug. 

It seems that dolphin enters an infinite recursion in DolphinMainWindow::preferredSearchTool and draws arbitrary amounts of memory (see valgrind massif log and my gdb session below).

STEPS TO REPRODUCE
1. Install Kubuntu 25.04

2. Perform a number of basic system configuration changes. I can unfortunately not specify exactly when the bug originated, but without success, I did the following trying to fix the issue:

* Roll back some custom settings that I made.
* Install newer plasma and KDE from the ubuntu-backports ppa.
* Shutting down the usual suspects that have caused headaches in the past (e.g., Baloo file search, akonadi and apparmor).
* Install and use Xorg instead of Wayland.
* Reset the custom user plasma configuration.
* Test with an entirely new user account without files.

3. Run dolphin and observe memory consumption. No need for any action/input.

OBSERVED RESULT

Dolphin, then plasma, ultimately the whole system will stall.

EXPECTED RESULT

Dolphin does its job with a limited amount of memory.

ADDITIONAL INFORMATION

Heaptrack indicates that there is a lot of memory allocation (from not actually working with dolphin):
total runtime: 3047.02s.
calls to allocation functions: 648550909 (212847/s)
temporary memory allocations: 212269633 (69664/s)
peak heap memory consumption: 581.62M
peak RSS (including heaptrack overhead): 862.61M
total memory leaked: 549.41M
suppressed leaks: 503.80K

I tried to verify the indicated leak with valgrind memcheck, but did not see a big leak.

However visuallizing the valgrind massif output, I found an apparent endless recursion  DolphinMainWindow::preferredSearchTool dolphinmainwindow.cpp:1315 which indirectly calls QArrayData::alocate2 to get memory.

To verify I entered a GDB session with breakpoint on this function:

(gdb) quit

I am attaching the logs of 
valgrind --leak-check=full --show-reachable=yes --track-origins=yes --trace-children=yes --log-file=memcheck.dolphin.log dolphin
and
valgrind --tool=massif --massif-out-file=massif.dolphin.1.out dolphin

I tried to move away /usr/share/applications/org.kde.kfind.desktop, because that should influence the behavior of DolphinMainWindow::preferredSearchTool , but no success.

Please let me know if/how I can provide more information.

Comment 1 Andreas 2025-12-02 14:33:16 UTC

This may provide some insight as it shows that dolphin infinitely removes and adds inotify watches (note that I tried rm ~/.cache/ksycoca6*; kbuildsycoca6 beforehand):

Comment 2 Andreas 2025-12-03 16:37:56 UTC

Adding an auditd watch on the ksycoca database seems to show that it is dolphin itself that is changing the file:

sudo auditctl -w /home/andreas/.cache/ksycoca6_en_8lUsizwh6dzjUZZpzrN6fC5HajA= -p wa -k filewatch

sudo aureport -f
