Strictly speaking, I do not understand either, because the error message 
is rather cryptic:

+ valgrind /scratch/harmonie/hm_home/MPI/bin/MASTERODB -maladin -vmeteo 
-eHARM -c001 -t60 -fh06 -asli
valgrind: mmap(0x726f000, 1796198400) failed in UME with error 22 
(Invalid argument).
valgrind: this can be caused by executables with very large text, data 
or bss segments.

However, I interpret this as "your executable (either code or data) is 
too large to be handled".
