Yeah I did some testing too and the only problems I saw (somewhere 
beyond 120 nodes) were just ulimits or MPI-settings stuff.

If you find out anything useful for others, please report here!

Oh BTW it's very strange you can resume such session with (seemingly) no 
problems. If you didn't already, you should look very closely in the log 
file and see if there are any clues there. Perhaps there is some error 
seen there that we should handle (or report) better.

Good luck,
