heartbeat errors

I have 4 servers running b3 and all of a sudden today one of the b3's decided to crash, so i restarted it and it runs a few seconds and stops with these errors.it was running fine for a few weeks. It seems to give the error when sending b3 master heartbeat.any idea's? The other 3 b3's are running just fine.
