Dear all,  
I am trying to do energy minimization of a simple water system. During energy minimization, at a few steps, I get this error **“One or more water molecules can not be settled. Check for bad contacts and/or reduce the timestep if appropriate. Wrote pdb files with previous and current coordinates”**. But after few steps, the process continues smoothly and energy is minimized nicely. Is it an actual error or just a message for that particular step. I have attached a screenshot for reference.  
Thank you
