help with log entry...
My backup server hung at 4 AM last night.The only message in /var/log/messages from that time until it was manually rebooted today is the following:
Sep 18 04:04:31 server2 kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000020
What does the above message mean? Does it give me anything to go on to know what to check and why the server might have crashed?
