many people, I don’t like to have my photos stolen from me and

the memory occupied by digikam. But by passing to the next
photo, the entire surplus of memory is not released, until
occupying the entire free memory. So the computer is rowing,

mémoire par Digikam, ou plutôt son nettoyage.<br>
J'ai repéré que Digikam verrouille la mémoire par le nombre de
photos qui incorporent du texte.<br>
Comme beaucoup, je n'aime pas que l'on me vole mes photos et
insère donc une signature dans celles-ci. Cette opération augmente
la mémoire occupée par Digikam. Mais en passant à la photo
suivante, la totalité du surplus de mémoire n'est pas relâché,
jusqu'à occuper la totalité de la mémoire libre. Alors le PC rame,
rame jusqu'au plantage.<br>
Ex d'hier (mem / 5969 Mo) : <br>
Sans activité : 762 M°<br>
Sans Digikam : 1295 M°<br>
Avec Digikam au lancement : 1458 M°<br>
Avec Digikam après 20 minutes mais sans aucune opértaion : 1665 M°<br>
Avec Digikam après 2 heures de manipulation de photos (200 photos)
: 2069 M° (utilisation de la mémoire ~stable ensuite >2500 M°)<br>
puis après insertion de texte (13 lettres) sur 5 photos : 2640 M°<br>
puis après insertion de texte (13 lettres) sur 21 photos : 4393 M°
puis jusqu'à 5200, 5300 M° puis plantage de Digikam ou du PC<br>
J'envoie également cet article à Digikam mais le retour est très
très long.<br>
J'ai essayé ceci, mais sans succès : sysctl -w vm.drop_caches=3<br>
ainsi que : echo "echo 3>/proc/sys/vm/drop_caches"<br>
Que faire ?</span>
