Process ends with "killed" when using brain server

[cpu_pirate]

May have solved my own problem, but in case anyone else runs into this issue in the future, it appears to be the amount of system RAM available on the host (client) PC, I only have 8Gb there and it appears with my current card configuration I needed a little over 10GB, disabling one of the GPU's seems to allow it to run.

Still wonder about the last question though.
