No, I'm not.

... because the tasks have created their output.

Great.

Do some counts from the output of orte-dvm provide some hints?
$ grep "Releasing job data.*INVALID" dvm_output.txt |wc -l
42
$ grep "ORTE_DAEMON_SPAWN_JOB_CMD" dvm_output.txt |wc -l
42
$ grep "ORTE_DAEMON_ADD_LOCAL_PROCS" dvm_output.txt |wc -l
42
$ grep "sess_dir_finalize" dvm_output.txt |wc -l
35
In other words, the "[netbook:XXXX] sess_dir_finalize: proc session dir does
not exist" message doesn't show up for the hanging ones, which could support
your question that the orte-dvm is at fault.
Gr,
Mark
