I am trying to dock a small molecule with holo dimer protein (153 aa, 1 Cu and 1 Zn per chain). I followed the Ligand Docking Tutorial and it all works fine until I try to generate more than ~50 output structures. Using both MPI and default builds, all 8 GB of RAM and 5 GB of Swap are slowly filled up until my linux system kills the program. Below I have listed different commands and how many strucures it generated before swamping memory. The basic options file and xml file is attached is attached.
