Memory Problem

[tk4223]

I am having a slight issue with the available memory on my titan, when i soft reset, i have a steady 22-24MB of memory for hours, however after two to three hours my memory suddenly drops to around 14 to 17MB. It doesnt matter if i use my phone alot or little.

I have no running programs showing in my running programs tab.

The apps that i have istalled and use are:
QuickMenu
HTC Home (N2As weather fix)
Effcom
LED Killer 3.1

Using the stock Alltel 2.14.671.3 ROM

Im also playing around with the Touch Cube, but i was having these issues long before that. Thanks for any help
