[Digikam-users] Batch Manager crashes due to memory exhaust

[Robert Zeller]

Hi Gilles,

my camera produces 36 Mpix raw-images, which typically have a size of 50
MBytes. When developing 6 images parallel I reach the my memory limit of
8 GB and DK crashes. So it seems to be time to upgrade my machine to 32
GB of memory. Anyway it would be nice to have an option to restrict the
number of cores BQM is working on.
Regards, Robert
