            Bug ID: 312092
           Summary: kded4 memory leak - RAM use is very high
    Classification: Unclassified
           Product: kdelibs
           Version: 4.9.3
          Hardware: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: grave
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: kdebugs at caseyconnor.org

I noticed significant slowness due to swap use, etc. RAM use is maxed out, and
I notice that kded4 is using >700MB of RAM. I assume this is a leak:

$ ps -FC kded4
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
casey     2148     1  1 402048 755716 0 14:59 ?        00:01:47 kdeinit4: kded4

This started maybe yesterday (haven't noticed it 'till then), so it might have
been a recent update that did it.

I am current with Kubuntu repository packages.

Rebooting resets the memory use. I am still checking to see how the growth
happens (e.g. all at once, gradually, associated with any particular actions,
etc.) It seems to continue and get larger and make the computer unusable.


Reproducible: Always

Steps to Reproduce:
1. boot up
2. observe that memory footprint is low
3. use the computer a while
4. observe that memory footprint is high
5. eventually rebooting is necessary

Kubuntu 12.10 on a Dell Inspiron 6000. I have many features disabled/turned off
(no desktop effects, no akonadi, no nepomuk, etc etc.)

Happy to provide more info.
