Red Flashing LED

[KTP]

currently my x10 is flashing a red LED, maybe 1 flash per second.
any idea what this is for?
i seem to have nothing in the notification bar and my battery is 83%
no missed calls, emails or texts and i dont have any apps that should cause this.

Mine flashes red when the battery is low, I know this doesn't help you but I think that's what it should mean!?

Could be low memory?
