3.01 crash, help with log analysis please


Im New to Multirotor and Ardu, but have a hexa on APM2.5 running 3.01.

I had a strange crash last time i flew and have looked at the attached dataflash log and can see that something weird happened at about line 6598, in the pitch and roll plots, command diverges from actual, but i dont know what has caused it. The copter was doing RTL and seemed Ok, then it drifted past the home position and then flipped out and crashed.

I have hopefully uploaded the Log below.

If someone could guide me through the log i would be very grateful.
