Dear Users,
I ran Regcm4 within West Africa domain and I got this error. Does anyone have solution to this?
Thank you.

mpirun has exited due to process rank 2 with PID 23167 on
node localhost.localdomain exiting improperly. There are two reasons this could occur:

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"
