MD crashes: how to restart

[Matthias Krack]

Hi Jörg,

CP2K uses the POSIX function rename of the OS to change the file name. Due 
to the documentation an error code 2 corresponds to 

#define  ENOENT       2 /* No such file or directory */

on my Linux box, i.e. the source file or the target file path does not 
exist.You may check the relevant errno*.h include file of your system to 
figure out the meaning of the error code.

HTH,

Matthias
