i have everything working (os, jivetalk, googlemaps, etc) i was watching some 2-4 min long videos on youtube and after the video is done playing my bb does a reset on its own (the red led indicator comes solid for about 3 seconds and the phone goes to the hourglass and restarts)

any reason why this happens? i have 20k mem when i check status and i don't seem to have a memory leak overnight as far as i can tell...
