Recently I have been getting a memory low icon when I have not added anything new to my Droid (I have the original Motorola Droid). I have tried moving some apps to my SD card and clearing the cache and data but still the icon reappears without reason. This icon is frequently accompanied by his friend, Cannot Receive Text Messages, Messages Full icon. Even when I erase messages---even at times when I erase ALL my messages, this does not necessarily clear the issue. I removed handcent thinking that since I was getting the messages stored twice (with handcent and with the factory messaging service) it would clear up the problem--and it did. Temporarily. I have also tried the old fashioned 'take the battery out' approach to no avail.
