            Bug ID: 501879
           Summary: Memory Leak with Kioworker
    Classification: I don't know
           Product: kde
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: zeebie at zeebie.net
  Target Milestone: ---

SUMMARY
There appears to be a memory leak in the kioworker process that causes
increasing memory usage over time without it being released, impacting system
performance until targeted by OOM Killer and terminated

STEPS TO REPRODUCE

Use Dolphin to perform file system operations, specifically accessing SMB
shares and performing searches for specific files.

Monitor the memory usage of the kioworker process using a system monitor tool
like htop or top.

Observe the increasing memory consumption by kioworker that is not released
even after tasks are completed.

OBSERVED RESULT
The kioworker process steadily consumes more memory over time without releasing
it, leading to a noticeable memory leak.

EXPECTED RESULT
The kioworker process should release memory after completing its task,
maintaining stable memory usage without excessive growth.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Garuda Linux 
KDE Plasma Version: plasmashell 6.3.2
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2

ADDITIONAL INFORMATION

The issue is primarily observed during regular file operations in Dolphin while
accessing networked shares via SMB.

Memory leak is not immediately apparent but becomes noticeable after extended
usage.

The process does not seem to release memory after completing tasks like file
transfers or searches.
