Yeah, you need the sketch name.
I found that wait() was required pretty much after every send. I don't why exactly, I suspect the the send commands were overrunning the previous send command.
I second this. Waiting after send can help some odd behavior.
I have also had nodes the performed well with debug turned on, then not work when it is off. The debug prints are slow in processor time and I think they act like a wait. If this happens, check where you have debug messages and try some waits there, especially if it is after a send.
