Hi,
My BJ was working fine about 25 days, and starting from today, raspberry pi keeps restarting every minutes, so in reality it stopped working. I don't know what caused the reboot, hardware, cgminer or the pi it's self. From the monitor, it can be any time, even last second it's hashing and received and accepted share, then suddenly rebooted.

Has anybody have the same issue. How should I diagnose this issue? Thank you very much for the help!
