Totally different subject. I have three Habs and three Goldrushes. I have them mixed with 3 running on a pc and 3 running on a Rpi. My issue is the Rpi. It seems to lock up and lose communication with the network after 3-4 hours. It needs to be physically reset. I use a data center so that really sucks. I have a similar issue with a pi on the old Drillbit miners. But for that one I bought one of those network enabled outlets that I can cut off power and restart power via the web. But those are not cheap.
My question is if anyone else has reset issues with their Rpi and if so how did you fix it. Bad SD card? Different hub or switch to router? Grasping here.
You can configure the watchdog to reboot the Pi when it hangs. I have only used the watchdog with peon on the Pi and it seems to have fixed the hang issue. Try get hold of a BeagleBone Black $55 from adafruit who also accept btc, they work much better then the Pi. (i have 2x Pi and 2x BBB)
There area few posts online saying the Pi flaw in the architecture that causes the USB to lock, which then also locks the network. Some say overclocking the Pi can help but it still locked up for me.
