X shuts down and reboots

Question

Has anyone experienced the phone shutting down and rebooting. I can have my phone sitting next to me and it will go to a black screen and the eye pops up and reboots.

Answer 1

Rebooting of the DX was the major point why I returned that phone.
I had my DX for 4 days and it was rebooting constantly, about 7 - 9 times a day.
VZ tech told me that it is a known issue with DX and therefore I returned it thinking to get Incredible.
However, my brother-in-law that has Incredible and his phone reboots too (though not as often as my DX). That makes me thinking what if problem is not a phone (Droid X) in particular, rather than Moto Blur skin or Android OS in general.
I was reading that rebooting may in fact be related to Advance Task Killer if it is being set to Auto-Kill mode as it could be killing some running processes which are required by OS.If Auto-Kill is disabled and applications are being killed manually it should resolve reboot problem.
DX hardware has 512 MB of RAM but in my case I was ending up with less than 50 MB (less than 10%) of RAM only after an hour of phone just sitting there without single application being touched by myself. I understand that about 200 MB is being used by OS and another 100 MB is being used by all essential subprocesses (Moto Blur) but that should leave me with 200 MB of RAM not 50. Those little pesky bloatware programs that VZ forces on you should be either disabled, uninstalled, or not being loaded into memory constantly.
In regards to controversy of needed or not Advance task killer, I am personally felling that I needed that just to kill all of the bloatware that VZ placed on that phone and which is being loaded constantly into memory. So as far as I am concern, issue with reboot is all VZ fault and that is why this is a "known issue" for them.
