[Digikam-users] DigiKam Lockup

[Mick Sulley]

Several times recently I have experienced DigiKam locking up my whole 
system.  I cannot identify a specific action, it seems to be fairly 
random when it happens.  In order to try to understand it better I have 
started running system monitor before I start DigiKam.

What I see is that when I start using DigiKam the processor and memory 
usage is fairly low but when the problem occurs it is using almost all 
of the memory (16 Gb) and half of the swap space (32 Gb).  The mouse 
movement is very jerky, Alt Tab does not work, any music playing has 
many gaps, etc.  It is still only using 1 or 2% of the processor.

This happens during fairly easy DigiKam operations, tagging faces, 
moving pictures, etc, I am not doing any bulk recognition or anything.

I am running Debian Jessie and DigiKam 3.5.0 using KDE 4.11.3

Questions -
Is there anything I can do to fix it?
Is there anything I can do to provide more information?
If I increase my memory from 16 Gb to 32 Gb is it likely to fix it or 
will DigiKam just use all of that when the problem occurs?

Thanks
Mick
