I can't reproduce this, how often does it fail? I've run it in a loop
hundreds of times here and not had one hang.
Off-topic I know but this is exactly the type of problem that padb is
designed to help with, if you could get it to hang and then run "padb
-axt" in another window on the same node and send along the output I'm
sure it would be of help.
