Dear David,
Thanks for confirming my believes regarding the use of the NETCDF-files.
I've carefully checked my job-file and the -O flag is always present before each run.
Moreover, the simulation actually starts and runs for many nanoseconds before the error message pops up (how many nanoseconds vary from simulation to simulation basd on the use of ig=-1) so based on this I wouldn't be related to the use of the -O flag right?
With kind regards, Björn

Your understanding of netcdf format is correct. However, the above message
looks like it is happening when write_nc_restart is called, i.e. when you
are trying to output a new netcdf restart file at the end of your new run.
Check your file names carefully. Unless you set the "-O" flag, amber will
not overwrite an existing file, which could lead to the above error if the
requested restart file already exists. But it could be some other
permissions problem as well.
