Hi all,
Here my NEB stops with a message in .error file:

One of the processes started by mpirun has exited with a nonzero exit
code.  This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.

PID 15498 failed on node n0 (127.0.0.1) with exit status 1.
