Andi,
your patch fixes the initial bug that stops sampling immediately after starting. The issue Eric mentions seems to be a different problem. I am also not able to reproduce this. Your patch on top of rc3 continues sampling at least for several minutes.
I will apply your fix.
Thanks Andi,
-Robert
