Sudden "low storage memory" warnng?

[bstep01]

All of the sudden, im getting the low storage space icon above. This has happened 2 other times. I do a hard reset when that happens. I checked my phone this morning, I had 120 mb internal memory, and now im down to 2.26mb of memory. My phone gets warm, battery drains. Nothing is running! Has anybody seen or heard of this issue?

Thanks!

Maybe some program is saving a ton of cache... try one of those cache cleaner apps.
