Problems with my 6800

[mort_subite]

So I recently flashed my 6800 myself and got everything working perfectly. However, the device has been erratically hanging and forcing me to soft reboot, as all other buttons become functionless and the OS halts. This usually happens after I've made a call, and sometimes when I'm going to create a text message. Other times it happens for what seems like no reason.
I have considered the notion that I foolishly packed too many programs into my ROM and this is adversely affecting performance in the form of conflicts that are causing the device to hang. I'm going to reflash the phone with a minimum of programs in the ROM and see if that helps, but I was curious for input from y'all Geeks to see if anyone has had similar problems.
I've heard a few negative reviews regarding the device hanging and requiring reboots, so hopefully this isn't that end of the problem.

Thanks in advance,

M.
