Failure to activate node zero in shared memory machine

I was running NAMD-CUDA 2.8 4JUN2011nb (a molecular dynamics
simulation code) successfully on nvidia
280.13-1. I am now bach to namd after a few months, on the same
macjhine, now nvidia 295.20-1 (which version matches debian amd64
xserver and all
libraries). First activating CUDA:

# nvidia-smi -L
# nvidia-smi -pm 1

then launching namd, node zero failure
