To determine how long the server had been running before it abended, enter the following command in the internal debugger:

# dd UpTimeInSeconds 4

The output will look something like this:

FC5EAC20   000170CB

The output contains the time the server was up in ticks. The value is in hexadecimal. In the above example, the value 000170CB is the number of ticks in hex. Convert the hex value to decimal by entering #zb in the debugger. Using the above example, you would enter:

# zd 170cb

In this case, the time would convert to 94411 ticks in decimal. To convert the ticks into days, divide by 88400. In our example, the server would have been up 1.06 days.
