Hah... you're right Phil as well, Phil, the battery voltage plays a huge part here. But I have also seen the micaz mote crash while testing file transfers from mote to mote, with both motes plugged into MIB520 boards. The file transfer worked great on tmote's, so I have yet to narrow down what the issue was with the micaz. Voltage? Some kind of flash/radio problem? Flash driver issues? I don't know, I just know that voltage seemed unlikely because those motes were plugged in. The hardware should be working as expected.

Call me crazy, but I'd say that the issue isn't mica hardware, but the fact that the batteries have a low voltage. Flash can pull a lot of current. Putting batteries under heavy load can cause them to behave sub-optimally (can't recover complete charge).
