server 2012 R2 -The computer has rebooted from a bugcheck

Question

I have server 2012 R2 and I get the following error

event id: 1001 - The computer has rebooted from a bugcheck.  The bugcheck was: 0x000000ef (0xffffe0014f4708c0, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 080323-17531-01.

And this is after the server restarted 4 times in the last 48 hours

event id: 41  - The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly

Hello there,

The error message you are encountering indicates that your Windows Server 2012 R2 system experienced a bugcheck (also known as a Blue Screen of Death or BSOD) with bugcheck code 0x000000EF. This bugcheck code indicates that a critical thread in the operating system's process has exceeded its allotted time to execute, causing a stop error.

Bugcheck codes are specific error codes that can help diagnose the cause of the system crash. In this case, the bugcheck code 0x000000EF suggests that the system's critical thread encountered a deadlock, meaning it got stuck waiting for a resource that was not released by another thread.

To troubleshoot and resolve this issue, you can try the following steps:

Check System Event Logs: Review the System Event Logs in Event Viewer (eventvwr.msc) to see if there are any other error messages or warnings that might provide additional information about the cause of the crash.

Check for Recent Changes: Did you recently install any new hardware, drivers, or software updates? If so, try rolling back the changes to see if the issue is resolved. Alternatively, update drivers and software to their latest versions.

Run Hardware Diagnostics: Perform hardware diagnostics to check for any hardware issues. Faulty hardware components, such as memory or disk drives, can cause system crashes.

Check for Overheating: Make sure your server's cooling system is functioning correctly. Overheating can lead to system instability.

Check for Malware: Run a full system scan using a reliable antivirus software to rule out the possibility of malware causing the crash.

Check for Disk Errors: Use the built-in Windows utility CHKDSK to scan for and fix any disk errors.

Check Memory: Use the built-in Windows utility Memory Diagnostic (mdsched.exe) to check for memory errors.

Check Windows Updates: Ensure that your system is up to date with the latest Windows updates and patches.

Update BIOS and Firmware: If applicable, update the BIOS and firmware of your server's motherboard and hardware components.

Disable Overclocking: If your system is overclocked, try disabling the overclocking settings temporarily to see if it resolves the issue.

Check Third-Party Drivers and Software: Third-party drivers and software can sometimes be the cause of system crashes. Consider uninstalling or disabling non-essential drivers or software to see if it helps.

If you are still unable to identify and resolve the issue, you may need to analyze the memory dump file (MEMORY.DMP) generated during the crash using debugging tools. This requires some advanced knowledge of Windows debugging and might be best done with the assistance of a qualified IT professional or Microsoft support.

Always remember to back up critical data regularly, especially when troubleshooting system stability issues.

Answer 2

Please run the DM log collector and post a share link into this thread using one drive, drop box, or google drive.

If the server is able to run the V2 log collector it will collect more useful log files for troubleshooting.
