Root Random continuous reboot

this has happened twice now. a app would freeze (maybe not sure its the app fault) then my thunderbolt would go into a continuous reboot cycle until i remove the battery.

i used revolutionary root, BAMF 1.0.3 rom. didn't flash my radio since im already Mr2.

any ideas? i do have quick boot on if that makes any diff.

VM heap size is maximum memory an application can consume; it does *not* mean it's total memory footprint, just how much *data* it can allocate at the same time. Therefore, the more resource-intensive application, the more heap it *requires* to run; this effect is very visible with LWP's and launchers which operate on large amounts of uncompressed bitmaps. Additionally, JIT pretty much requires large VM heap as the basic idea behind just-in-time optimizer is to trade memory efficiency for operating speed.

VM heap is also roughly the biggest chunk of per-app virtual memory space that kernel can't "fake", share between multiple apps, silently drop and reload when accessed or do any of the other memory management tricks that allow to squeeze multiple apps that would each require hundreds of megabytes of memory under naive (e.g. DOS- and win95-like) memory allocation schemes into a handful of MBs that are actually available. Since it cannot be made disappear from physical memory to make room for something else without corrupting app state, the more complex apps grow, the more often they have to be killed -- or force closed in Android terminology.

So basically it is how much memory you allow an app to allocate to itself, the larger it is the more memory a single app can hold and prevent other apps from having. The general idea is the larger the better because apps then don't have to drop things to allow other apps to run, the issue would be the larger you set it to the less apps you can have running before the OS decides to kill them.

is there a number i can set it at that generally works well and i can set it and forget it?

k, ill leave it alone. but back to the original post.
any idea on the continuous reboots?
im not new to overclocking computers and have been doing it since duron 600mhz days so i understand the whole overclocking/cooling and needing more voltage to stay stable.
but after rooting, rom flashing i never messed with any cpu/voltage settings so i know its not overclocked but as far as voltage goes i don't know if for some reason its under voltage possibly...

so any other ideas?

Try the newest version of the rom. I think 1.0.5 is available. It could be that the one you are running was built off of MR1 which caused the reboots to be more pronounced in most phones. You could also upgrade the radios, I doubt that would be the issue but couldn't hurt. I like the 3rd GB leak.

Oh and I ususally assume when someone posts in the root section here for the first time they have no tech past because a lot of people don't and it usually helps more to assume someone knows less they do than to confuse them to the point of wanting to revert back to something they are used to.

I would expect you will have more reboots if you have already been having them. The newer Sense roms are built off better leaks than the older ones and are more stable. I expect once the GB OTA is leaked or released they will be updated quickly to include things like the VM notification fix.

For user apps use titanium to backup data as well, I don't suggest backing up system app data as the system app may change between rom flashes. You could see if there is an export to SD card option for the playlists. Also you really need to get the paid version of titanium the free version requires you to press install and okay for each app IIRC but the paid version doesn't prompt for that which shortens the restore time quite a bit.

ah that would be useful, i did think it was a pain in the ass to manually say ok for every app.
