Hi,
I am a begginer in using NAMD. I need some help.
Im was running a process with 1000 steps of minimization.
Misteriously at step number 594, the minimization do not go on.
The program do not stoped and the process was still running for close 48 hours beyound this step.

I kill the process and start it again.
The same problem happen again at the same step.

Any idea???

Here I paste part of the log file:
