Has anyone tried a large amount of gridseeds on cgminer? I am trying 28 of them on a rasberry pi and it stops accepting shares and eventually crashes after about 2 minutes. Running 28 instances of cpuminer works great, stable, and multipool reports right about where the hash rate should be.
Mine's been stable since upgrading to the "next" kernel (3.10.30+):
sudo apt-get install rpi-update
sudo BRANCH=next rpi-update
