Margins and timestep are very important parameters to keep from such an error.
Use: margin 3.0

But the problem now is that I am trying to run the first "production" run (step7_production.inp) and when I use the restart files from last step 6.6_equilibration.inp, I still get only the step7 xst file with 0 steps and error persists. Please guide me to how to solve this problem , knowing that I am running using NPT and don't want to change to NVT. I a still learning NAMD and have seen that margin increase should not affect my simulation, just the "performance", but I am not sure to which value it should be set/ how to determine best value that doesn't;t impede or affect my simulation. Sincerely, Asma Feriel
