Solution Type Troubleshooting Sure Solution 1017776.1 : Handling Microsoft Windows Hangs on an X64 Sun[TM] Microsystems systems.
PreviouslyPublishedAs 228996 To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Sun x86 Systems Summary This document addresses failures in the system stability which result in a hang state. The definition of hang in this context is when the (hardware) system continues to run, but doesn't answer to any user actions locally and remotely. The Screen maybe completely frozen or the mouse cursor could be the only component that is still responding to user interaction. In some case the mouse pointer is displayed, but you cannot move it. In other cases the computer does not respond either to mouse movements or to any keyboard input. The system will not offer any prompt or display any messages. NOTE: This document is not for any unwanted reboots or BSoD (Blue Screen of Death) - the aim of this document is mainly to show the user how to collect the system informations in such case. Symptoms - System Hangs Steps to Follow Steps to follow Step 1. clarify the kind of hang you are facing Firstly, you need to verify and clarify which kind of hang you are facing, and indeed if your system has actually hung. Refer to <Document: 1012991.1> "How to check if your x64 platform "system hang" actually is a system hang"
We will qualify an Unrecoverable hang state by all of these conditions:
Explorer is responsible of the main Windows GUI. This is the Window Manager. If Explorer is " not responding " you may not be able to move any windows but the mouse cursor may still respond. The Caps Lock keyboard key should be working properly (led off/led on). Using hotkeys CTRL+ALT+DEL should also launch successfully the Task Manager. The Operating system should answer to the pings (if not firewalled). The web and network services should be able to answer to the remote queries as expected (if any of these services are configured). For Windows 2003 versions, the out-of-band management Special Administration Console (SAC) should also be reachable locally or remotely. Step 2. What to do if there is an "Unrecoverable system deadlock" All you can do is to manually reboot your system to the Windows safe user mode in order to collect system informations on the last issue and arrange some parameters for the troubleshooting purpose. To restart your system please refer to <Document: 1008398.1> "How to Reset an x64 System" Once you have performed the reboot, force the system to boot in Safe mode using the F8 key after the complete BIOS initialization boot process. Now you can follow the instructions in Step 4 How to collect system informations and configure it for troubleshooting. While rebooting if you get a "Blue Screen of Death (BsoD)(crash/panic) please refer to <Document: 1017889.1> "Analyzing System panics on x64 platforms running Microsoft Windows" Step3. What to do when you have a "Recoverable system state" The first action to try is a CTRL+ALT+DEL keyboard sequence in order to get the access to the Graphical Identification and Authentication (GINA) and click on the "Task Manager" button. Here are more details on the steps to follow : 1. Be sure to verify your system state by following the instructions in <Document: 1012991.1> "How to check if your x64 platform "system hang" actually is a system hang" 2. For any Windows version use CTRL+ALT+DEL to run the "Task Manager". 3. If the "Task Manager" appears, go to the Applications tab and check the list of not responding programs. 4. Try to "end task" for all the "not responding" programs. 5. You can also go to the "Processes" tab and use the "End Process" to kill any "not responding" process. The most common action will be to kill any Explorer.exe procesess and re-launch at least one Explorer task from the "Applications" tab by using the "New Task" button just by entering "explorer" followed by the enter key to the command prompt. For Microsoft Windows 2003 only, you may also have the possibility to use the out-of-band Special Administration Console (SAC). See the "Microsoft Windows 2003 specific references" part at the end of this document for further informations. If the issue is happening again you should :
Step 4. Collect system information and configure it for troubleshooting In order to understand what's going on or if the system remains unstable, you will have to reboot your operating system to the Safe user mode following some of the methods as described bellow.
If possible use the Start menu on the bottom left corner and select the Shut Down option (and for Windows 2003 you will also have to select Restart option),then click the OK button) If the main Windows GUI is unavailable or not responding you can try to use the Windows Task Manager by issuing a CTRL+ALT+DEL. To do so, go to the Users tab and select your logged user and hit the "Logoff" Button. When you reach the GINA Logon screen you can select the "Shutdown" button in order to restart your system. Alternatively you can go to the Applications tab for the Task Manager and click to the "New Task" button and enter the following shell command :
shutdown /f /r If none of these actions work, please refer to <Document: 1008398.1> "How to Reset an x64 System"
While rebooting, wait until you pass the BIOS screen and reach the Microsoft Windows black screen showing "Starting Windows" where you'll have to quickly hit the F8 keys to stop auto-booting and enter the advanced boot options menu. Then select the "Debugging Mode" or "Safe Mode" option and press enter to boot it. If you can't get to the Safe mode, please consult the Microsoft knowledgebase Safe-Mode Boot Switches for Windows Boot.ini File, article ID : 239780 Once you are logged to Windows, please collect the information as outlined in <Document: 1010936.1> "Microsoft Windows and Linux operating systems: How to obtain troubleshooting information". By the way, if while booting you get a BSoD (crash/panic) please refer to <Document: 1017889.1> "Analyzing System panics on x64 platforms running Microsoft Windows" We will now describe some methods that require prior setup before a basic reboot:
Here are some instructions on the many possible ways to setup your Windows installation in order to collect system informations :
Edit in the Registry the following key : HKLM\System\CurrentControlSet\Control\CrashControl\NMICrashDump (DWORD) set to value of 1 Then reboot Windows to its normal way. Once you got the hang, hit your NMI button to generate a crash and its dumpfile.
Go to the SAC --if available-- anytime you got a system hang and use the crashdump command.
Find out how to setup your Windows installation in order to generate a memory dump while your system is having a hang state. Read this Microsoft knowledgebase documentation : "Windows feature lets you generate a memory dump file by using the keyboard" article ID : 244139 http://support.microsoft.com/default.aspx?scid=kb;EN-US;244139
Then Press Ctrl-C (or click Debug->Break) ? this breaks into target system. Once you are into the target system, run the .crash command to force the crash. For any Windows versions, see the Microsoft knowledgebase documentation: ID 315263 "How to read the small memory dump files that Windows creates for debugging" http://support.microsoft.com/kb/315263 Get Microsoft WinDbg software and its documentation at http://www.microsoft.com/whdc/devtools/debugging/default.mspx You will find more helps about WindDbg from the Microsoft support website and the internal help pages from the software itself.

Once you have generated the panic dump please refer to < Document: 1017889.1 > "Analyzing System panics on x64 platforms running Microsoft Windows" for further actions. At this point, if you have validated that each troubleshooting step above is true for your environment, and the issue still exists, further troubleshooting is required.
