why is my storage memory so low??

[mlevin77]

I'm running a cooked ROM on my Verizon XV6700. Over time (and I've rebooted etc.), my storage memory has gotten down to 0.5 MB, while my program memory is at 22 Megs. I've got an SD card, so I try to install everything I can to that, and I don't (knowingly!) store anything sizeable in memory. I'm getting a "low memory" error when I boot and when I sync (over-the-air) with an exchange server. What's going on? Are there cached or temporary files somewhere from browsing or mail connections to an Exchange server that can be cleaned up? How do I find the main culprits causing this?

thanks,

Mike
