The issue is my code crashes at my view.StillRender() but it happens only when using mpirun and pvbatch. If i just use pvbatch without mpirun, the crash does not occur. > Code: http://paste.ubuntu.com/5960325/ > Crash: http://paste.ubuntu.com/5960330/ > CMakeCache.txt: http://paste.ubuntu.com/5960331/ Thanks, ~Brian
