Arista also noticed this error. We saw this when we were running the test_reboot_supervisor in test_voq_disrupts.py. This narrows it down to a reboot issue. Will update if we get more details on this.

The case 4 described in PR #20024 aligns with the error we are seeing. I assume that the follow up PR mentioned in the description would be addressing this error @zbud-msft ?
