About once every two or three days, I get a strange notification in my bar. It's a red SD card icon, and it tells me that my "Database storage is getting low." I have 1.5 gb free on my partition, 15 free on my SD card and about 13 free on my internal storage, so I'm pretty confused. Usually, it goes away within 30 minutes - an hour but now, it's been here for a day. Restarting does not help, I've tried on multiple occasions. I also went to "manage applications" and tried clearing caches and what not, no luck. Help?
