That line of code is here: https://github.com/open-mpi/ompi/blob/v1.10.2/orte/mca/plm/lsf/plm_lsf_module.c#L346 (Unfortunately we didn't catch the rc from lsb_launch to see why it failed - I'll fix that).
So it looks like LSF failed to launch our daemon on one or more remote machines. This could be an LSF issue on one of the machines in your allocation. One thing to try is a blaunch from the command line to launch one process per node in your allocation (which is similar to what we are trying to do in this function). I would expect that to fail, but might show you which machine is problematic.
