Could you please let know if we have any solution to sort below panic alerts and can we know what would have caused for the panic.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Logs:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Mon Jan 16 17:30:44 GMT [lhrbod-fsxxh03:mgr.stack.saved:notice]: Reboot with saved panic information in log file&amp;nbsp;&amp;nbsp; Mon Jan 16 17:30:44 GMT [lhrbod-fsxxh03:mgr.stack.string:notice]: Panic string: page fault (supervisor read, page not present) on VA 0x28 cs:rip = 0x8:0xffffffff843eceb3 rflags = 0x10246 in SK process Auth09 on release 8.1.3P3&amp;nbsp;&amp;nbsp; Mon Jan 16 17:30:44 GMT [lhrbod-fsxxh03:mgr.stack.at:notice]: Panic occurred at: Mon Jan 16 17:14:14&amp;nbsp; 2023&amp;nbsp;&amp;nbsp;&amp;nbsp; Mon Jan 16 17:30:44 GMT [lhrbod-fsxxh03:mgr.stack.proc:notice]: Panic in process: Auth09&amp;nbsp;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Unfortunately, your Ontap (7-mode) version is way out-of-date and for such errors (panic) it is suggested to contact support and upload the core file. However, I don't think that is an option available in your case. There could be multiple causes, only after analyzing the core-dump file that the engineering/support could advise what might have caused it.&amp;nbsp; Recommendation will be to upgrade the OS, i.e data ontap from 8.1 to 8.2 (last upgradable version).&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Related Kb (May be not your issue)&lt;/P&gt;&lt;P&gt;System panic with PANIC: page fault (supervisor read, page not present)&lt;BR /&gt;&lt;A href="https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Systems/FAS_Systems/System_panic_with_PANIC%3A_page_fault_(supervisor_read%2C_page_not_present)" target="_blank"&gt;https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Systems/FAS_Systems/System_panic_with_PANIC%3A_page_fault_(supervisor_read%2C_page_not_present)&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Upgrade:&lt;/P&gt;&lt;P&gt;&lt;A href="https://library.netapp.com/ecm/ecm_get_file/ECMP1511541" target="_blank"&gt;Data ONTAP 8.2 Upgrade and Revert/Downgrade Guide For 7-Mode (netapp.com)&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;8.2 download : (You can do NDU from 8.1 to 8.2)&lt;/P&gt;&lt;P&gt;&lt;A href="https://mysupport.netapp.com/site/products/all/details/dataontap8/downloads-tab/download/30092/8.2.5P5/downloads" target="_blank"&gt;NetApp Support Site - Product Details - Download&lt;/A&gt;&lt;/P&gt;</description>
