jstefanop, Have you tried using zRAM to help solve this problem? I've heard it works well in situations where RAM is limited. Here's an example script, https://github.com/novaspirit/rpi_zram
Also looking forward to the full node update. Will this have the ability to easily enable solo mining straight from the dashboard? Also would be nice to have optional tor integration for added privacy.
I finally got around to setting up my two Apollo's with wifi and put them in the garage, but noticed that when running them both I had to change the default hostname 'futurebit' of one otherwise it didn't work, like there was a conflict or something. Maybe it would be easier to have the ability to change the hostname from the web interface, I had to ssh into the device from the terminal.
