What to Do If the System Crashes
-
Write down the system console messages.
-
If a system crashes, making it run again might seem like your most pressing concern. However, before you reboot the system, examine the console screen for messages. These messages can provide some insight about what caused the crash. Even if the system reboots automatically and the console messages have disappeared from the screen, you might be able to check these messages by viewing the system error log, the /var/adm/messages file. For more information about viewing system error log files, see How to View System Messages.
-
If you have frequent crashes and cannot determine the cause, gather all of the information you can from the system console or the /var/adm/messages file and have it ready for a customer service representative to examine. For a complete list of troubleshooting information to gather for your service provider, see Checklist for Troubleshooting a System Crash.

Check to see if a system crash dump was generated after the system crash.
Caution - Do not remove important system crash information until it has been sent to your customer service representative.
