This came up on my screen some seconds ago while i were trying to connect bluetooth between the PC and the phone. It has happend once before too. When i press OK it just come up again, after a minut the phone just died, i couldnt close it with the on/off button. It seems to be the ram memory its talking about because there is plenty of memory free on the C: drive. Have this happend to someone else?
PS: My firmware version is 4.37.
Edit: The first time it happend i didnt even have bluetooth one, but someone sent me a SMS some seconds before.
