Does this happen when you run without '-am ft-enable-cr' (so a no-C/R
run)?
This will help us determine if your problem is with the C/R work or
with the ORTE runtime. I suspect that there is something odd with your
system that is confusing the runtime (so not a C/R problem).
Have you made sure to remove the previous versions of Open MPI from
all machines on your cluster, before installing the new version?
Sometimes problems like this come up because of mismatches in Open MPI
versions on a machine.

I met the same problem with this
link:http://www.open-mpi.org/community/lists/users/2009/12/11374.php
in the link, they give a solution that use v1.4 open mpi instead of
v1.3 open mpi. but, I am using v1.7a1r22794 open mpi, and met the
same problem.
here is what I have done:
my cluster composed of two machines:nimbus(master) and
nimbus1(slave), when I run mpirun -np 40 -am ft-enable-cr --
hostfile .mpihostfile myapplication
on the nimbus, and it doesn't work, it shows:

A daemon (pid 10737) died unexpectedly with status 255 while
attempting
to launch so we are aborting.
There may be more information reported by the environment (see above).
This may be because the daemon was unable to find all the needed
shared
libraries on the remote node. You may set your LD_LIBRARY_PATH to
have the
location of the shared libraries on the remote nodes and this will
automatically be forwarded to the remote nodes.

mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.
