I can not find enough information to debug an error.

Hello,
I'm using OASIS3 coupling atmospheric model (HARMONIE) and ocean model (NEMO).
I have generated new oasis files (masks.nc, grids.nc and areas.nc) and now the coupling crashes. Even with a debug level of 20 in namcouple, I don't find the exact reason of the problem.
The last lines of debug.02.000000 (for Harmonie model side) say this:
...
(oasis_coupler_setup) DEBUG cb:initialize coupler 1 1 T
(oasis_coupler_setup) DEBUG ci:initialize coupler 1 1
(oasis_coupler_setup) DEBUG ci:part1 info 1 1 1 230400 450

(oasis_coupler_setup) DEBUG ci: inquire mapfile rmp_surfex_to_oceanx_DISTWGT.nc F
------ ENTER (oasis_map_genmap)
-------- ENTER (oasis_io_read_field_fromroot)
So it enters oasis_io_read_field_fromroot but only enters because it doesn't write any read message after which is strange because it prints messages from oasis_debug_enter and there is nothing in between. These are the lines at the beginning of oasis_io_read_field_fromroot:
....
call oasis_debug_enter(subname)
! expects to run only on 1 pe.
! if (iam == master_task) then
if (OASIS_debug >= 5) then
write(nulprt,*) subname,' read ',trim(filename),' ',trim(fldname)
endif
...
And it doesn't write the read message (?)
In the Harmonie backtrace the last routine in the list is sfx_oasis_define:
...
[myproc#1,tid#1,pid#1236516]: 2145 MB (maxheap), 217 MB (maxrss), 0 MB (maxstack), walltime = 1725349568.30s

[myproc#1,tid#1,pid#1236516]: SUPHMSE_SURFACE
[myproc#1,tid#1,pid#1236516]: SFX_OASIS_DEFINE
In particular in this line:
...
call oasis_enddef(ierr)
And in this routine, looking for its messages in debug.02.000000 I see that it calls oasis_coupler_setup() and doesn't come back from this call as the messages after it don't appear in the debug log file. The calling must follow this sequence: oasis_enddef -> oasis_coupler_setup -> oasis_map_genmap -> oasis_io_read_field_fromroot
The other model log debug file doesn't show relevant information. These are the lasf few lines:
(oasis_coupler_setup) DEBUG cb:initialize coupler 1 1 F
(oasis_coupler_setup) DEBUG cb:initialize coupler 1 2 T
(oasis_coupler_setup) DEBUG ci:initialize coupler 1 2

(oasis_coupler_setup) DEBUG ci:part1b 10 5572 31 0
(oasis_coupler_setup) DEBUG ci:avect1 initialized
------ ENTER (oasis_mpi_barrier)
I don't find any other relevant information in any oasis debug file.
Thank you,
Cheers,
Juan Carlos.

Hi Juan Carlos,
On which platform do you run? Can I get access to your rundir so to have a look at what is happening?
