It turns out they are related. We only get these errors when we
daemonize the orteds. The fix for this is in the trunk and it will be
in 1.3.2 (but it is not in 1.3.1 or 1.3.0).

You can workaround this in 1.3.0 and 1.3.1 with this parameter:

--mca orte_leave_session_attached 1

This will prevent the daemonizing and the mca_common_sm_mmap_init error
should go away. I will also add this to the existing bug report.
