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.
