The hardware health status section within ESXi is displaying outdated update timestamps for all hosts. The hardware health information refreshes only at irregular or random intervals instead of updating automatically at expected intervals.
7.0.x
This behavior occurs due to a bug in the "vpxa" code.
This issue will be resolved in ESX 9.1, and the fix is expected to be included in upcoming patch releases for 9.0 and 8.x.
Note: There is no fix available for version 7.x.
