[HTC Sensation] Yank555:
Consider reviewing the lowmem settings, you have loads of lowmem issues in there, that resulted eventually in an "Unable to handle kernel paging request", thus the kernel had no other choice than to reboot.

And the same apps keep getting killed again and again and again, that will also drain the battery at that.

Here is a "cleaned" version of your log, what lead to the reboot is highlighted in red (almost last line) :
