The OFED warning about registration is something OMPI added at one point when we isolated the cause of jobs occasionally hanging, so you won't see that warning from other MPIs or earlier versions of OMPI (I forget exactly when we added it).

The problem you describe doesn't sound like an OMPI issue - it sounds like you've got a memory corruption problem in the code. Have you tried running the examples in our example directory to confirm that the installation is good?

Also, check to ensure that your LD_LIBRARY_PATH is correctly set to pickup the OMPI libs you installed - most Linux distros come with an older version, and that can cause problems if you inadvertently pick them up.

I have a simple, 1-process test case that gets stuck on the mpi_finalize call. The test case is a dead-simple calculation of pi - 50 lines of Fortran. The process gradually consumes more and more memory until the system becomes unresponsive and needs to be rebooted, unless the job is killed first.
In the output, attached, I see the warning message about OpenFabrics being configured to only allow registering part of physical memory. I’ve tried to chase this down with my administrator to no avail yet. (I am aware of the relevant FAQ entry.)  A different installation of MPI on the same system, made with a different compiler, does not produce the OpenFabrics memory registration warning – which seems strange because I thought it was a system configuration issue independent of MPI. Also curious in the output is that LSF seems to think there are 7 processes and 11 threads associated with this job.
The particulars of my configuration are attached and detailed below. Does anyone see anything potentially problematic?
