2.6.1, MacPro, High Sierra: SYSTEM RAN OUT OF APPICATION MEMORY

[eight]

In Isadora 2.6.1, MacPro, 16 gb RAM, two AMD FirePro D500 video cards.

When I get this dialog, my typical state is Camer Feed Black Syphon -> SYPHON -> GPU PostProcessing -> SYPHON -> Isadora. In addition Isadora always plays a few HAP video files, and has a webcam usb feed.

System Memory Consumption is always below 3 GB (well below 16 GB available in the system), plenty of SSD HD space.

My theory is that maybe  GPU memory is being exhausted, however, the GPU Usage History, CPU Usage in the activity monitor always show low load in all departments.

One strange thing is that out of two GPUs in the computer, only one GPU is always used according to the GPU Usage History monitor.

Any pointers would be appreciated.

@eight your second gpu is compute only, so you won't see much there, that leaves one 3gb card, pretty easy to max out.
