Hello guys, so with the latest commit (not version, commit), Minera should work fine with lot of large data too (I mean with many G-Blades connected).
This isn't definitely confirmed yet (I had only one confirmation) but if you had problems with many G-Blades, you should give a try to the latest commit:
cd /var/www/minera
sudo git fetch --all
sudo git reset --hard origin/master
sudo ./upgrade_minera.sh
I would like to thank Sandor so much, he did the PHP patch to get this working, so the beer goes to him this round!

PS
@unamis76 you should definitely look at the cpuminer.log to understand what's happening on your env (a good try it's also run the command directly into the terminal without the screen options)
Just saw this after my last post, I may give this a try once I see some feedback from others. Right now I need a few days of stable earnings out of the blades!
