It sounds like you are either overclocked too high or undervolted too low with a set at boot option turned on.

 

Google is your friend Test: How changing the max amount of memory per VM Heap can effect your ROM (Cyanogen) Ryan Olson

 

Just stole this from another forum

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.

 

Yea, whatever it's set at already leave it there. There's no need to change it

 

+1 I just leave it alone but set it to 32 if you feel you have to change something, I would suggest tweaking something else instead

 

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.

 

Yeah, the license is a good purchase once you decide to root and start flashing roms. I nearly stopped flashing roms at one point before I actually purchased the titanium pro key.

 

Yep, the paid version has a whole bunch of batch commands for backing up and restoring apps. that and the market doctor are all I use in tibu.

 

You should be wiping before you flash. Wiping data in recovery is the same thing as a factory reset

 

I would suggest not using ROM Manager. It will only cause problems. Manually flash and wipe in recovery and you'll save yourself numerous headaches
