This issue occurs when vCenter Server cannot log in to one of the ESX hosts in the cluster, causing a VPXD core dump.
To resolve this issue, refresh the vCenter Server Inventory:
- In the vCenter Server Inventory, right-click on the host causing the error message in the VPXD logs and select Remove.
Note: When the ESX host is removed from the inventory, all performance data is lost.
- Re-add the ESX host to the vCenter Server Inventory.
