Please open a case with GTAC so they can continue to investigate this with Engineering.

We would need someone from GTAC that knows the bug number. I was able to find similar (old) feedback of a similar issue for other customers searching this community, but unfortunately I didn't see a tracking number (https://community.extremenetworks.com/extreme/topics/xos-12-6-1-3-stack-crashes-after-1555-days-upti...). 1555 days of uptime then the bug bringing dual Master state.

Thank you Stephane, is there any article, available so that will get business approvals for down time

I believe you are hitting a known issue at around 1500 days of uptime, where the Master and Backup do not see each other and you have a dual Master happening. That has been fixed for a long time, but I assume not in your current release (upgrade to the latest). A reboot would solve that for another 4 years...
