Root error logging

[20GT]

My phone reboots, it will do it about twice a week
it will freeze then reboot.
no particularapp running that it does it on
going on for about 6 months now, ever since i rooted

is there an app that will show me error logs of what happened
just before this reboot?

Android doesn't store logs to device memory, but keeps it just in RAM, so you have to use aLogrec to save the logs periodically, of course this will slow down the phone and drain battery.
