In fact, I also have tried to configure the OpenMPI with this:
./configure --with-sge --with-openib --enable-mpi-thread-multiple
--with-threads --with-hwloc --enable-heterogeneous --disable-vt
--enable-openib-dynamic-sl --prefix=/home/jescudero/opt/openmpi
And the problem is still present

btl, you need to remove --mca mtl mxm from command line.
Have you compiled OpenMPI with rhel6.4 inbox ofed driver? AFAIK, the
MOFED 2.x does not have XRC and you mentioned
"--enable-openib-connectx-xrc" flag in configure.

I have a 16-node Mellanox cluster built with Mellanox ConnectX3
cards. Recently I have updated the MLNX_OFED to the 2.0.5 version.
The reason of this e-mail to the OpenMPI users list is that I am
not able to run MPI applications using the service levels (SLs)
feature of the OpenMPI driver.
Currently, the nodes have the Red-Hat 6.4 with the kernel
2.6.32-358.el6.x86_64. I have compiled OpenMPI 1.6.4 with:
./configure --with-sge --with-openib=/usr
--enable-openib-connectx-xrc --enable-mpi-thread-multiple
--with-threads --with-hwloc --enable-heterogeneous
--with-fca=/opt/mellanox/fca
--with-mxm-libdir=/opt/mellanox/mxm/lib
--with-mxm=/opt/mellanox/mxm --prefix=/home/jescudero/opt/openmpi
I have modified the OpenSM code (which is based on 3.3.15) in
order to include a special routing algorithm based on "ftree".
Apparently all is correct with the OpenSM since it returns the SLs
when I execute the command "saquery --src-to-dst slid:dlid".
Anyway, I have also tried to run the OpenSM with the DFSSSP algorithm.
However, when I try to run MPI applications (i.e. HPCC, OSU or
even alltoall.c -included in the OpenMPI sources-) I experience
some errors if the "btl_openib_path_record_info" is set to "1",
otherwise (i.e. if the btl_openib_path_record_info is not enabled)
the application execution ends correctly. I run the MPI
application with the next command:
mpirun -display-allocation -display-map -np 8 -machinefile
maquinas.aux --mca btl openib,self,sm --mca mtl mxm --mca
btl_openib_ib_path_record_service_level 1 --mca
btl_openib_cpc_include oob hpcc
I obtain the next trace:

Does anyone know what I am doing wrong?
