promiscuous mode

[shaling]

Hi,
I have several moteinos which transmit structs, some between each other and some to a gateway (moteino+arduino mega). I had recently added a moteino in promiscuous mode to get a gateway setup running on the side using python. All moteinos just send (so not using send.withretry).  However, in python, my logging shows that nodes sometimes disappear for up to 300s. I am sending 3 times (1/s) every 20 seconds, so it's as if a node goes dark for a period. I am sending uptime in the radio packets so the nodes have not reset. I have timeout timers on the arduino mega gateway which I think don't see this behavior. Could this be due to the use of promiscuous mode? I can't see any other obvious difference between the setups. The mega is also displaying a webpage, so I really expected that to miss packets and not the python gateway running on x86 hardware.

Thanks.
