Default [Q] Storage Memory Full error

Is anyone else experiencing this problem where you can't even receive text messages, emails or anything anymore when this problem occurs? I seem to get this problem while using the GPS for a while. I do not even have much applications installed for this to even happen.

I have this same problem with no solution with two devices so far that i switched out for.

I used eugene's vibrant rom as the rom and ryanza's lagfix. Is there anyway that it is the rom's problem or the phone problem?

A couple of people who experience the same problems with so far no solutions:
