Reproducible: Always

Steps to Reproduce:
1. Use a large set of photos >6000 (*.jpg, raw, *.tif's each round about 120MB)
2. work with face detection
3. set person names to the face tags

Actual Results:  
digiKam fill all the available memory (1MB in 2seconds) an swap space
16GB swap space is on SSD, photos on classic HD, 16GB RAM full used

Expected Results:  
normal RAM use

face recocnition DB is 2,2GB !

--- Comment #1 from Gilles Caulier <[hidden email]> ---
It's same problem than bug #338176, but your valgrind trace is interresting.

Please report your trace directly in but #338176. No need to have duplicate
entry in bugzilla.
