Okay, this is still a problem. This node keeps dieing at 1am every day, most times without an error in the log. I'd appriciate any help in tracking down why.
Additionally, I don't understand why 0.7.x using *way* more RAM than 0.6.x and 0.8.x, from a top or ps perspective. I'm now watching the JVM memory and it seems to be more in line with 0.6.x but the MAX heap is crazy high (28G on my servers).
