Well, due to the fact that my mind is full of code right now an i could use some distraction, i'm gonna tell you (all) a bit about (last_)kmsg :D

But first to your Q: no, it doesn't say "OC error" or something like that. You need to see the it in its context ;)

Here an example for a kernel panic due to too much OC'ing:

Now a bit general stuff about kmsg. The file /proc/kmsg is the kernel's logfile. it tracks everything the kernel does. (At least what is programmed to be logged ;) ) last_kmsg is the "finished" log of the last session. Meaning: at every reboot of the phone, the "old" kmsg gets renamed to last_kmsg and a new log gets created.

The log strings inside the log are usually mostly understandable for everyone. Try it out ;) Take a look into it and i will guarantee you, you will understand a lot of things in there :)

let's take a little deeper look in it:

Then there comes the most interesting stuff, like the hidden/reserved memory, the clocks, battery init, the memory (a.k.a. RAM) "partitions" (reserved memory, allocated memory and the "usual" memory) and finally booting all available processors

Then there comes some general stuff, like modules, drivers and other things

I sadly don't have a log of a normal shutdown, but it would include logs about unmounting modules, partitions and some other shutdown related stuff.

I hope you guys can understand now a little bit why we need those logs to fix issues. ;)
