App that will catch a reboot culprit?

I am rooted but stock and have a really clean setup. I get a reboot a couple times a day when really working the phone. It seems to be triggered when a screen rotation happens along with multiple other apps running at the the same time. I have not narrowed it to a specific app though.

Any one find anything that would be helpful?

I've never used one, but wouldn't one of the logcat apks do that? Search the market for logcat.

Good luck.

If you have "terminal emulator" you can run "top" and it will show processes , you might be able to catch it in there .
/var/log usually holds any crash logs .
Never mind , "logcat" does that for you .

There's an app called WatchDog that monitors for 'runaway' apps that might be able to catch the culprit prior to the reboot.

I know you said you were 'stock' but which kernel and radio are you running? Generally reboots are a kernel issue.
