cisco 3845 router was in hung state

Querry 1:

I have a cisco 3845 router on yesterday evening , the router was in hung state and we are not able to reach the internet. so Made the standby as active and kept the device isolated. As troubleshooted the device found that the device has generated with crash info stating that the device got rebooted due to software. Can any one confirm about the crash info ?
