[digikam] [Bug 325712] New: Face tagging has massive memory leak

            Bug ID: 325712
           Summary: Face tagging has massive memory leak
    Classification: Unclassified
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Face Management
          Assignee: [hidden email]
          Reporter: [hidden email]

When you tag faces digikam eats all available meory in short time.
I'll add a screentshot of a memory graph.

Bug #323253 might be related.
Because of the bug report I deleted recognition.db and all works fine. Also
tagging, but after editing/tagging hundreds of faces the proplem reappear.
recognition.db is 184M big now.


Reproducible: Always

Steps to Reproduce:
1. Go to 'people' view
2. Start tagging faces
3. Doesn't matter if you stop tagging - memory consumption goes on
Actual Results:  
In less than 5 minutes (often in much shorter time) all available memory is
used: 8G Ram + 8G swap.

Expected Results:  
Don't eat all my memory :-)

I'm running Digikam on Kubuntu saucy, KDE 4.11.2
The Kubuntu packages of Digikam 3.3.0 showed the same bahaviour.
I compiled Digikam from sources which is 4.0.0-beta1
Build date: Oct 5 2013 (target: debugfull)
Rev.: 5983eeb8adcbcb3e4d32ec1cdf6304b3ae7f258a


digiKam version 4.0.0-beta1

Additional information: You can not end digikam when this happens. The gui
disapears, but the process ist still running and eats memory. sigterm ends
digikam.

I am facing the same issue, running openSuSE Tumbleweed with Kernel 3.12 and
KDE 4.11.3.
The face recognition requires a lot of memory in general and there is no switch
or so to limit it.

As the guys before me wrote Digicam will eat up all available memory even swap.
I upgraded my system today to 16GB RAM plus 120GB SSD swap. When working with
face recognition for 5000 pictures is it just a matter of memory bandwith until
Digikam allocated more than 40GB of memory.

Read, write and delete to RAM continues but no progress in operation can be
detected. For me it stay in status "Applying face changes" for hours when I
made changes to 100-200 pictures.
