While using both AOKP and XenonHD, when I update my apps, most of the time the phone will crash/reboot. When it comes back up, the notifications will tell me that the apps didn't update. I'll repeat the process and they will update. ... until the next time I see updates and try to update the apps. Then the situation repeats.
I switched from AOKP to XenonHD thinking it may have been something buggy in the ROM, but I still have the problem. The phone is not hot afterwards either.
