Ok, thanks Ralph. Start the DVM with: orte-dvm --report-uri dvm_uri --debug-devel And then run the following script. The "serial /bin/date" and the "parallel sleep 1" are fine. The "parallel /bin/date" shows the hanging. #!/bin/sh for i in $(seq 42): do # GOOD #orte-submit --hnp file:dvm_uri -np 1 /bin/date #orte-submit --hnp file:dvm_uri -np 1 /bin/sleep 1 & # BAD orte-submit --hnp file:dvm_uri -np 1 /bin/date & done wait
