[gmx-users] System blowing up at restart

[Marlon Sidore]

It actually went on a few steps before blowing up, it didn't blow up
directly at restart.
Does that mean it simply blew up because of the system ? It always blows up
a little time after restarting though, and that's strange given the time it
ran the first time.

gmx dump doesn't say anything special, should I include its output in a
file here ?

The restarted log file says:
"Restarting from checkpoint, appending to previous log file.

it then continued for a few steps before blowing up. It's basically the
same as the beginning of the log file (for the first run).
