PhotoLab 4.3.0.57 takes all memory

When editing Nikon NEF files I have experienced that PhotoLab takes nearly all my 16 GB RAM plus a lot of swap area.
It has happened three times in a week now and my record is 60 GB (RAM + Swap) memory used by PhotoLab.
I use an Apple iMac 2017 with 16 GB of RAM, 4.1 GHZ processor and Mojave OS.
Once when this happened my computer locked totally and must be shut down with the power button on the back and pushed again to start the computer.
This is a serious bug and must be removed.

Hi, @Bjoran - have you opened a ticket at support.dxo.com? That’s the best way to get this fixed, because DxO will need test files and info from your computer.

Thank you Greg, I will do that.
