Recently someone reported issues which were traced back to
the fact that the files that sm uses for mmap() were in a
/tmp which was NFS mounted; changing the location where their
files were kept to another directory with the orte_tmpdir_base
MCA parameter fixed that issue for them.
Could it be similar for yourself ?
