[Tinyos-help] Rebooting of mote

Phil,

Every now and then when I would re-program my motes using Deluge, there
would occasionally be one instance where every node got the new image and
rebooted except one mote.  The one mote would just consistently reboot
itself.  Does the above explanation fit what was happening in my case?
